The class with the greatest frequency is the class "15.2 - 19" with a frequency of 7. The class with the least frequency is the class "0 - 3.8" with a frequency of 2.

To construct a frequency distribution with 5 classes for the given data representing time spent reading a political blog in a day, we need to determine the class intervals and calculate the frequency, midpoint, relative frequency, and cumulative frequency.

First, we find the range of the data:

Range = Maximum value - Minimum value

Range = 19 - 0

Range = 19

To determine the class width, we divide the range by the desired number of classes:

Class width = Range / Number of classes

Class width = 19 / 5

Class width ≈ 3.8

Now, we can construct the frequency distribution table:

Class          Frequency   Midpoint   R. Frequency   C. Frequency

0 - 3.8           2              1.9                2/20 = 0.1           2

3.8 - 7.6        4              5.7                4/20 = 0.2           6

7.6 - 11.4      4              9.5                4/20 = 0.2           10

11.4 - 15.2    3              13.3              3/20 = 0.15         13

15.2 - 19       7              17.1              7/20 = 0.35         20

By organizing the data into classes and analyzing the frequencies, we can gain insights into the distribution of reading time and identify the most and least common time intervals spent on reading the political blog.

Explanation:

a) The mean of the population is given by:

Mean = (1 + 3 + 5 + 7) / 4 = 4

Therefore, the mean of the population is **4**.

b) There are six possible samples of two that can be drawn from the population:

{1,3}, {1,5}, {1,7}, {3,5}, {3,7}, {5,7}

The mean of each sample is:

{1,3}: (1+3)/2 = 2

{1,5}: (1+5)/2 = 3

{1,7}: (1+7)/2 = 4

{3,5}: (3+5)/2 = 4

{3,7}: (3+7)/2 = 5

{5,7}: (5+7)/2 = 6

Therefore, the means of all possible samples are:

2, 3, 4, 4, 5, 6

c) The sample mean of all possible samples can be calculated as follows:

Sample mean = (2 + 3 + 4 + 4 + 5 + 6) / 6 = 24 / 6 = 4

The sample mean is equal to the population mean. This is because the sample size is small and all possible samples have been considered. In general, as the sample size increases and more samples are considered, the sample mean will approach the population mean .

Kitchen and Excuses are predicate. In linguistics and its subfields, the word "predicate" is used in one of two contexts.

The first regards a predicate as only the main content verb or accompanying predicative expression of a clause, while the second sees it as everything in a conventional declarative sentence other than the subject.

As a result, the predicate of the statement Frank likes cake is loves cake according to the first definition. According to the second meaning, the same sentence's predicate is only the content verb "likes," with Frank and cake serving as the predicate's arguments.

The predicate gives details about the subject, including who or what it is, what it is doing, and how it behaves. A nexus is a relationship between a subject and its predicate.

Thus, Kitchen and Excuses are predicate. In linguistics and its subfields, the word "predicate" is used in one of two contexts.

Without understanding the exact content, context or scope of the dictionary that you're talking about, it is challenging to determine the exact position of the word "buccaneer." However, using simple logic, as per the alphabetical order, the word "buccaneer" can likely be positioned between the words based on the order of their starting alphabets.

For example, if the words "bubble" and "bucket" are already present in that particular dictionary, the word "buccaneer" can be placed between them, and it would follow "bubble" and precede "bucket".

The precise positioning of "buccaneer" would rely on the words that are already there in the dictionary and the sorting rules used by the publisher which can include (and not be limited to)- the consideration of spaces, special characters, capitalization, etc.

The cost of goods sold for the month of October using the FIFO method is $11,490 and the cost of the ending inventory is $6,840.

FIFO is one of the most commonly used inventory accounting methods. FIFO stands for First-In, First-Out, and it means that the first inventory items that enter a warehouse or storage location are the first to leave.

FIFO is often used in industries where products have an expiration date, like food and beverage, and it's also popular with companies that sell items that can quickly become obsolete, like technology or fashion companies.

Here, we are given the following transactions related to Sandra’s Purse Boutique and we need to calculate the ending inventory and cost of goods sold using the FIFO method.

Date Transactions Units Unit Cost Total Cost October 1 Beginning inventory 6 $820 $4,920 October 4 Sale 4 October 10 Purchase 5 $830 $4,150 October 13 Sale 3 October 20 Purchase 4 $840 $3,360 October 28 Sale 7 October 30 Purchase 8 $850 $6,800

We will calculate the cost of goods sold and ending inventory step by step using the FIFO method as follows:

As we are using FIFO, the first goods purchased are assumed to be sold first, and therefore, the cost of goods sold is calculated by using the unit cost of the oldest purchase transactions. Cost of goods sold (COGS) = Cost of oldest inventory * Units sold from oldest inventory to newest inventory

First, we will calculate the cost of goods sold for the first sale of 4 units on October 4. The first 4 units of inventory sold are from the beginning inventory of 6 units, which were purchased at a unit cost of $820.

Therefore, COGS = 4 * $820 = $3,280

Similarly, we will calculate the cost of goods sold for the second sale of 3 units on October 13. The first 2 units of inventory sold are from the beginning inventory of 6 units, which were purchased at a unit cost of $820. The remaining unit is from the purchase of 5 units on October 10, which were purchased at a unit cost of $830.

Therefore, COGS = (2 * $820) + (1 * $830) = $2,470

Finally, we will calculate the cost of goods sold for the third and final sale of 7 units on October 28. The first 2 units of inventory sold are from the beginning inventory of 6 units, which were purchased at a unit cost of $820. The next 4 units of inventory sold are from the purchase of 4 units on October 20, which were purchased at a unit cost of $840.

The remaining unit is from the purchase of 5 units on October 10, which were purchased at a unit cost of $830. Therefore, COGS = (2 * $820) + (4 * $840) + (1 * $830) = $5,740

Hence, the total cost of goods sold for the month of October using the FIFO method is $3,280 + $2,470 + $5,740 = $11,490

Now, we will calculate the ending inventory for the month of October. The ending inventory will include the remaining units that were not sold. We will first calculate the total units available for sale by adding the beginning inventory and the purchases made during the month.

Total units available for sale = Beginning inventory + Purchases

Total units available for sale = 6 + 5 + 4 + 8 = 23 units

Now, we will calculate the ending inventory using the FIFO method. The ending inventory will include the newest units purchased during the month. Units sold during the month = 4 + 3 + 7 = 14 units.

Therefore, the remaining units in the inventory = Total units available for sale - Units sold during the month

Remaining units in the inventory = 23 - 14 = 9 units

The 9 units in the ending inventory are from the last purchase of 8 units made on October 30, and the remaining unit is from the purchase of 4 units made on October 20.

Therefore, the total cost of the ending inventory using the FIFO method = (8 * $850) + (1 * $840) = $6,840

Therefore, the cost of goods sold for the month of October using the FIFO method is $11,490 and the cost of the ending inventory is $6,840.

Teaching the aim of developing new social patterns within the context of the sociology of education requires a comprehensive and interactive approach in the classroom.

Some strategies that could be used to effectively teach this aim:

1)Introduce case studies: Presenting real-life case studies that demonstrate social patterns and their consequences can help students understand the importance of developing new social patterns.

By analyzing these cases, students can identify existing social patterns, evaluate their impacts, and brainstorm potential alternatives.

2)Encourage critical thinking: Foster critical thinking skills by engaging students in discussions and debates about current social patterns and their implications.

Encourage them to question the status quo, challenge existing norms, and explore alternative social arrangements.

This can be done through open-ended questions, group activities, and analyzing conflicting viewpoints.

3)Collaborative projects: Assigning collaborative projects that require students to propose and develop new social patterns can be an effective way to engage them in active learning.

Students can work in groups to identify social issues, research potential solutions, and create action plans for implementing new social patterns.

This hands-on approach encourages creativity, teamwork, and problem-solving skills.

4)Guest speakers and field trips: Inviting guest speakers from various fields, such as sociology, education, and community organizations, can provide students with real-world insights into the development of new social patterns.

Organizing field trips to relevant community organizations or institutions can also give students the opportunity to observe and learn from initiatives that aim to create positive social change.

5)Reflective activities: Incorporate reflective activities, such as journaling, class discussions, or personal presentations, where students can express their thoughts, insights, and personal experiences related to social patterns.

Encourage them to critically reflect on their own behaviors, attitudes, and the potential impact they can have on social patterns.
