All of the following are true about data science and big data except: a.Digital data is growing at the rate of 2.5 quintillion bytes per day b.Data scientists use skills in data management, statistics, and software development c.No digital data is stored in traditional databases d.Data science involves preparing, manipulating, and analyzing large amounts of digital data
Answer:
Option C
Explanation:
All of the following are true about data science and big data except No digital data is stored in traditional databases
Reason -
Data generated in current time is of large size and is also complicated. Traditional data bases such as SQL databases etc. are not capable to store data that is changing at a fast pace and has huge volume, veracity, variety and velocity. But big data platforms such as Hadoop can store big data and process it speedily and easily.

Write a function (Stars) that uses a variable which's you can hardcode or pass its address in ECX to print stars equal in number to that variable.
So if the variable had 12, the program should print
************
Sample main() code
mov al,230;
mov [number],al
call Stars;
jmp end
If you want to use AX you can increase the number of * you can print, here is what the main would look like:
mov ax,5000;
mov [number],ax
call Stars;
jmp end
Stars:
push ebp ; save the base pointer
mov ebp, esp ; set the base pointer to the current stack pointer
mov eax, [ebp+8] ; load the parameter into eax
print_loop:
cmp eax, 0 ; compare the value of the parameter with zero
jle end_print_loop ; jump out of the loop if the value is less than or equal to zero
push eax ; save the value of eax on the stack
mov eax, '*' ; set eax to the character code for the asterisk
push eax ; save the value of eax on the stack
call putchar ; call the putchar function to print the asterisk
add esp, 8 ; clean up the stack by adding 8 bytes
sub eax, 1 ; decrement the value of eax
jmp print_loop ; jump back to the beginning of the loop
end_print_loop:
pop ebp ; restore the base pointer
ret ; return control to the caller
To call this function from the main program and print 12 asterisks, you can use the following code:
mov ecx, 12 ; load the parameter (12) into ecx
call Stars ; call the Stars function
This will print out 12 asterisks (************) to the console.
What does the standard deviation of a set of data tell you?
O A. The smallest data value
B. Whether the data are spread out or not
O C. How many data points there are
O D. The maximum value of the data
SU
Answer: It tells us about how our set of data is spread out as compared to our mean or expected value.
Explanation: Note: Standard deviation is represented by Greek Letter sigma.For example: A teacher in a class of particular students takes a learning ability test from the students. Average or mean marks of students is 52 with +/- 10 marks. Then 1σ (Sigma = standard deviation) it means 1 standard deviation = 68% students will lie in between 52 + 10 =62 marks and 52-10 = 42 marks region. 2σ (2 standard deviation) means among the students 95% of them will lie between 52 + 20 =72 and 52-20= 32 marks region.3σ (3 standard deviation) means 99.7% of the students will lie in the region where 52 + 30 = 82 and 52 – 30 = 22 marks region. So for 3σ (3 Standard Deviations), only 0.3% of the total students deviate +/-30 marks from the average. It means 0.15% students will have marks less than 22 and 0.15% students will have marks greater than 82. In the schematic attached, I have tried to make you understand through a diagram. Please refer to the schematic 1. It tells us about the how our set of data is spread out as compared to our average or mean. And distance from mean can be calculated through number of standard deviations that the data is how much below or above the average.For example:For 1σ 68% students will come under the curve of “Average Learners” and rest of 32% will come under the curve of “Poor Learners” and “Very Talented Learners”.For 2σ 95% of the students will come under the curve of “Average Learners” and rest will come under the curve of “Poor Learners” and “Very Talented Learners”.For 3σ 99.7% of the students will come under the curve of “Average Learners” and rest of 0.3% will come under the curve of “Poor Learners” and “Very Talented Learners”.

What will be the different if the syringes and tube are filled with air instead of water?Explain your answer
Answer:
If the syringes and tubes are filled with air instead of water, the difference would be mainly due to the difference in the properties of air and water. Air is a compressible gas, while water is an incompressible liquid. This would result in a different behavior of the fluid when being pushed through the system.
When the syringe plunger is pushed to force air through the tube, the air molecules will begin to compress, decreasing the distance between them. This will cause an increase in pressure within the tube that can be measured using the pressure gauge. However, this pressure will not remain constant as the air continues to compress, making the measured pressure unreliable.
On the other hand, when the syringe plunger is pushed to force water through the tube, the water molecules will not compress. Therefore, the increase in pressure within the tube will be directly proportional to the force applied to the syringe plunger, resulting in an accurate measurement of pressure.
In summary, if the syringes and tube are filled with air instead of water, the difference would be that the measured pressure would not be reliable due to the compressibility of air.

Python question
The following code achieves the task of adding commas and apostrophes, therefore splitting names in the list. However, in the case where both first and last names are given how would I "tell"/write a code that understands the last name and doesn't split them both. For example 'Jack Hansen' as a whole, rather than 'Jack' 'Hansen'.
names = "Jack Tomas Ponce Ana Mike Jenny"
newList = list(map(str, names.split()))
print(newList) #now the new list has comma, and apostrophe
Answer:
You can use regular expressions to match patterns in the names and split them accordingly. One way to do this is to use the re.split() function, which allows you to split a string based on a regular expression.
For example, you can use the regular expression (?<=[A-Z])\s(?=[A-Z]) to match a space between two capital letters, indicating a first and last name. Then use the re.split() function to split the names based on this regular expression.
Here is an example of how you can use this approach to split the names in your list:
(Picture attached)
This will give you the output ['Jack', 'Tomas', 'Ponce', 'Ana', 'Mike', 'Jenny', 'Jack Hansen']. As you can see, the name "Jack Hansen" is not split, as it matches the pattern of first and last name.
It's worth noting that this approach assumes that all first and last names will have the first letter capitalized and the last names capitalized too. If this is not the case in your data, you may need to adjust the regular expression accordingly.
