Constructing Normal Quantile Plots. In Exercises 17−20, use the given data values 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.
Braking Distances A sample of braking distances (in feet) measured under standard conditions for a sample of large cars from Data Set 14 in Appendix B: 139, 134, 145, 143, 131.

ANSWER:Answer :
Step 1 of 1 :
Given Braking Distances A sample of braking distances (in feet) measured under standard conditions for a sample of large cars from Data Set 14:
139, 134, 145, 143, 131.
First sort the data by arranging the values in order from lowest to highest.
131,134,139,143,145
x-values |
131 |
134 |
139 |
143 |
145 |
Here n = 5
Then we have to identify the cumulative areas to the left of the corresponding values.
