Question

Need to show all work like calculator step.s

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...
