Use the given data values (a sample of female arm circumferences in centimeters) to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution.

40.3

34.8

31.8

38.2

44.2

List the z scores for the normal quantile plot.

Normal Quantile Plot

Step-by-step explanation:

We are given the following in the question:

40.3 , 34.8 , 31.8 , 38.2 , 44.2

Formula:

where are data points, is the mean and n is the number of observations.  

Sum of squares of differences = 92.352

Formula:

The attached image shows the normal quantile plot.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
