All of the given dependent variables would be appropriate outcomes to examine with logistic regression. Logistic regression is used when the dependent variable is categorical, meaning that it falls into distinct categories or groups.

Base salary increase as a percentage of base salary can be converted into a categorical variable based on a specific threshold (e.g., increase vs no increase, increase above a certain percentage vs below). Bonus eligibility is already a binary variable (eligible or not eligible) and would be a suitable candidate for logistic regression. Bonus amount, however, would not be appropriate for logistic regression since it is a continuous variable and cannot be easily converted into categorical data. A regression analysis such as linear regression could be used to examine the relationship between the continuous bonus amount variable and the independent variables.

In the case of the listed dependent variables, "bonus eligibility" is already binary and would be a good candidate for logistic regression. For "base salary increase" and "bonus amount", these variables could be transformed into binary outcomes by setting a threshold value and categorizing the outcome as "increased" or "not increased" or "received bonus" or "did not receive bonus", respectively. With these transformations, both variables could also be analyzed with logistic regression.

A technique called simple random sampling involves choosing a random group of individuals from a predetermined population.

A selection of participants from a population is chosen at random by the researcher using simple random sampling, a sort of probability sampling.

Every person in the population has the same chance of being chosen.

Then, data are gathered from as much of this randomly selected subgroup as possible.

A straightforward random sample, where each participant has an equal chance of being selected, selects a small, random portion of the entire population to represent the entire data set.

Using techniques like lotteries or random draws, researchers can generate a straightforward random sample.

Therefore, a technique called simple random sampling involves choosing a random group of individuals from a predetermined population.

The formula for conditional probability is:

P(A|B) = P(A and B) / P(B)

where: P(A|B) is the probability of event A occurring given that event B has already occurred

P(A and B) is the probability of both events A and B occurring

P(B) is the probability of event B occurring

a. P(AB) = 0.35

b. P(AB) = 0.06

c. P(EF) = 0.81

a. P(AB) = P(A) * P(B|A) = 0.5 * 0.7 = 0.35

b. P(AB) = P(A|B) * P(B) = 0.15 * 0.4 = 0.06

c. P(EF) = P(E|F) * P(F) = 0.8 * 0.95 = 0.76

In this case, we are given the following information:

P(A) = 0.5

P(B) = 0.7

P(A and B) = 0.35

Using the formula for conditional probability, we can calculate P(A|B) as follows:

P(A|B) = P(A and B) / P(B) = 0.35 / 0.7 = 0.5

This means that the probability of event A occurring given that event B has already occurred is 0.5.

We can use the same approach to calculate P(AB) and P(EF).

In conclusion, the answers to the questions are:

In statistics, the "central tendency" refers to a single value which represents middle or center of a set of data. The 3 common measures of central tendency are named as mean, median, and mode.

When scores have a central tendency, it means that most of the scores in a set of data are clustered around a particular value.

For Example, if we have a data set of test scores, and most of the scores are around 70, then 70 would be the central tendency of the data set.

The central tendency is an important concept in statistics because it provides a way to summarize a large set of data with a single value.

The Lagrange polynomial basis L = {l0(t), l1(t),..., ln(t)} is a set of polynomials with specific properties: li(t_i) = 1 for all i = 0, 1,..., n, and li(t_j) = 0 for all i, j = 0, 1,..., n, where i ≠ j. This basis allows you to represent any polynomial p(t) in Pr by a linear combination of the Lagrange polynomials in the basis L.

Polynomials are mathematical expressions consisting of variables and coefficients, often used in algebra and calculus. In this context, we are considering polynomials of degree n or less, denoted by Pr.

Lagrange polynomials are a type of polynomial that form a basis for Pr. This means that any polynomial in Pr can be expressed as a linear combination of the Lagrange polynomials. The Lagrange polynomial basis is formed from a set of n + 1 distinct points in R, denoted {to, t1, ..., tn}.

Each Lagrange polynomial, denoted li(t), has the following properties:
- li(ti) = 1 for all i = 0, 1,..., n
- li(tj) = 0 for all i, j = 0, 1,..., n, i + j.

In other words, each Lagrange polynomial is equal to 1 at its corresponding point ti, and is equal to 0 at all other points. These properties ensure that the Lagrange polynomials are linearly independent and form a basis for Pr.

This means that a linear relationship exists among the variables.

When the data points on a scatterplot cluster along a straight line, it indicates that there is a linear relationship between the two variables being plotted.

The scatterplot visually shows that as one variable increases or decreases, the other variable also increases or decreases in a proportional manner, following a straight-line pattern.

The correlation coefficient is an estimation of the strength and direction of the linear relationship between two variables. A positive correlation coefficient indicates that as one variable increases, the other variable also increases, while a negative correlation coefficient indicates that as one variable increases, the other decreases.

The magnitude of the coefficient implies the strength of the relationship, with a value of 1 showing a perfect positive correlation and a value of -1 showing a perfect negative correlation.

The thickness of the clay layer, which drains only from the upper surface, can be determined based on the consolidation settlement observations. With 50% of consolidation settlement occurring in 1 hour for a 25 mm thick specimen, and a total primary consolidation settlement of 35 mm occurring over many years, the thickness of the clay layer is approximately 87.5 mm.

The consolidation settlement of a clay specimen can be used to estimate the thickness of a clay layer that drains only from the upper surface. In this case, the observed settlement data provides valuable information.

Firstly, we know that 50% of the consolidation settlement occurs in 1 hour for a 25 mm thick clay specimen. This is an important parameter for calculating the coefficient of consolidation (Cv) using Terzaghi's theory. From the Cv value, we can estimate the time required for full consolidation settlement.

Secondly, we are given that the same clay settles 10 mm over 10 years and eventually settles a total of 35 mm over a longer period. This long-term settlement is known as the total primary consolidation settlement. By comparing this settlement value with the settlement data from the oedometer test, we can determine the thickness of the clay layer.

To calculate the thickness, we can use the concept of the consolidation settlement ratio. The ratio of the total primary consolidation settlement to the consolidation settlement at 50% completion is equal to the ratio of the total thickness to the thickness at 50% completion. Applying this ratio, we can determine that the thickness of the clay layer, which drains only from the upper surface, is approximately 87.5 mm.

d)Using α = 10%, the degree of freedom as 14, and a one-tailed t-test (since we want to test if the average SAT score for computer science majors should be higher than 1143).

we reject the null hypothesis and conclude that there is evidence that the average SAT score for computer science major should be higher than 1143.2.

The 90% confidence interval for µ can be calculated as follows:  
\($\bar{x} \pm t_{0.05, 14} * \frac{s}{\sqrt{n}}$  $= 1173 \pm 1.761 * \frac{85}{\sqrt{15}}$ $= 1173 \pm 50.94$\)
