Pls only answer if you know it:) The numbers are 19, 36, 24, 40, 17, 43, 30, 31, 37, 28, 45, 32, 16. What are the first quartile, median and third quartile to this data set?

a) 21.5, 31, 37
b) 21.5, 31, 38.5
c) 24, 31, 38.5
d) 24, 31, 37

The answer is b

Step-by-step explanation:

The reason being that I just did it myself on a lesson and got it right.

The answer is B

Step-by-step explanation:

You order them from least to greatest- 16, 17, 19, 24, 28, 30, 31, 32, 36, 37, 40, 43, 45.

Then you find the middle number or the median- 31

Then you go to the left of the medain and get the first quartile- 19, 24 (You have to find the mean of these two numbers- 21.5)

Then you go to the right of the medain and get the third quartile- 37, 40 (Again you must find the mean of these two numbers- 38.5)

Last you would put them in the order needed.

Hope this helps! :)

step-by-step explanation:

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
