A substance abuse counselor wants to demonstrate the effect of situational stress on alcohol cravings. He recruits two groups of men who are similar in respect to history of alcohol use and demographic variables. He divides them in to two groups. In one group(n=11), the men are exposed to a stressful situation and then asked to complete a measure rating their alcohol cravings on a scale from 0-10, where 0 representsno cravings and 10 represents intense cravings. In the second group (n=10), the men are exposed to a neutral situation and asked to complete the same measure. What test and graph should I create to find out if a stressful situation result in more intense alcohol cravings than a non-stressful situation?

A quality control engineer at Shell visits 80 gas stations and collects a fuel sample from each. She measures the sulphur content in the gas and sorts the samples into 4 different batches. She finds: 19 samples with less than 180 ppm sulphur, 20 samples with between 180 and 230 ppm, 23 samples with between 230 and 280 ppm, and 18 samples with more than 280 ppm. Does the sulphur content of gas follow a normal distribution with a mean of 230 ppm and a standard deviation of 50 ppm at the 5% significance level
Online Sales Inc. has outsourced their customer service and wants to construct a control chart for determining whether the 10 customer service employees in the company they’ve hired are under control regarding the number of unsatisfied customers. Online Sales Inc. has sampled 100 service calls from last year for each customer service employee, with the following results: Customer Service Employee Unsatisfied customers 1 20 2 33 3 15 4 28 5 17 6 25 7 18 8 26 9 16 10 28 Analyze the data using a p-chart that would provide a 97% confidence interval, identifying the control limits and customer service employees, if any, that are outside the control limits.
