Step 1

The Normal Quantile plot:

Normal Quantile plot is graph that plot observations against corresponding z-score values. The x axis of the normal quantile plot represents the observations and y axis represents the z-scores.

Step 2

g.)The Normal Quantile plot of the number of defective items:

Here, the number of defective items produced on the assembly line per day is counted for a random sample of 20 days. The x-axis represents the number of defectives and y-axis represents the z-scores corresponding to number of defectives. The Normal Quantile plot is given below:

Step 3

h) Checking whether the samples are coming from an approximately normal population.

If the points in the normal quantile plot are in a straight line then it can be concluded that the samples are coming from a normal populat...
