Using Technology to Generate Normal Quantile Plots. In Exercises 13–16, use the data from the indicated exercise in this section. Use computer software (such as STATDISK, Minitab, Excel, or StatCrunch) or a TI 83 / 84 Plus calculator to generate a normal quantile plot. Then determine whether the data come from a normally distributed population.

Exercise 11

Solution 15BSC

By using the Normal Quantile Plot to determine whether the data come from a normally distributed population.

The systolic blood pressure measurements of males normal quantile plot are:

By using MINITAB, we draw the normal quantile plot of systolic blood pressure with the help of following steps:

1) Import the given data into the worksheet.

2) Select Probability Plot from the Graph and choose Single option.

3) Select Graph variable option.

4) Click Ok.

The systolic blood pressure measurements of males normal quantile plot suggests that points are normally distributed. The patterns of the points are reasonably close to straight line. We conclude that systolic blood pressure measurements of males data values are coming from population having a distribution that is normal.
