Chapter 8, Problem 1BSC(choose chapter or problem)
Requirements Twelve different video games showing alcohol use were observed. The duration times of alcohol use were recorded, with the times (seconds) listed below (based on data from “Content and Ratings of TeenRated Video Games,” by Haninger and Thompson, Journal of the American Medical Association, Vol. 291, No. 7). What requirements must be satisfied to test the claim that the sample is from a population with a mean greater than 90 sec? Are the requirements all satisfied?

Step 1:
Here the following purposes of test are given by:
1) The sample is a random,which is assume that 12 different video games were selected randomly.
2) Here n=12,which is not greater than 30.
So we must determine whether the sample is normal distribution or not. For this we draw normal probability plot.
Here are the Steps to find normal probability plot are as follows.
i) store data in minitab in one column as shown below.
