A random sample of 22 STAT 250 students was collected and the file size of Data Analysis 2 was recorded. The data was measured in megabytes. The instructors of the course claim that the file size will be different from 5 megabytes. Consider the population of all file sizes to be right-skewed. Using a = 0.01, is there sufficient evidence to conclude that the mean file size of Data Analysis 2 is different from 5 megabytes? Conduct a full hypothesis...

A researcher conjectures that cities in the more populous states of the United States tend to have higher costs for hospital rooms. Using “city data” that accompany this text, select a random sample of ten cities from the six most populous states (California, Texas, New York, Florida, Pennsylvania and Illinois). Then take a random sample of ten cities from the remaining states in the data set. For each of the twenty cities, record the average daily cost of a private...

GMU officials are trying to determine if they are using the correct number of campus shuttles for the number of students who use them. If the proportion of students who use the shuttles is significantly different from 0.28, the officials believe they will have to either remove or add a shuttle to the fleet. In a random sample of 444 people taken from the population of all individuals associated with GMU (including faculty, staff, and students) it was discovered that...

2. Along with exam scores, the instructor also collected data concerning employment status of the sample of 45 World Campus students. In that sample of 45 students, 32 students reported they were employed full-time. A. Use Minitab Express to construct a 95% confidence interval to estimate the proportion of all World Campus students who are employed full-time. If assumptions were met, use the normal approximation method. Remember to include all relevant Minitab Express output and to clearly identify your answer....
