The first one:
In a random sample of 100 World Campus Students (i.e., trials, n) at Penn State, 27 indicated they were full-time (i.e., events).
Use the information above, Minitab, and the five-step hypothesis testing procedure outlined below to determine if there is evidence that the population proportion of all World Campus students who are full-time is different from 0.5.
The second one:
A researcher is studying the average cost of traveling for a college student. As part of their research, they would like to learn more about the average yearly money spent to travel to and from home by air. In a random sample of 125 students, the mean travel cost by air was $1,750, with a standard deviation of $435. Use these sample data to answer the following questions.
Use the information above, Minitab, and the five-step hypothesis testing procedure outlined below to determine if there is evidence that the population mean air travel cost per college student is different from $1600 per year.
