you have been asked to study the mean yearly tuition at private four-year colleges and universities across the United States. You are interested in making some decisions concerning this population parameter. You select a random sample of 50 universities from this population. The mean tuition at these universities is found to equal $18,205. You still have reason to believe that the population standard deviation of the tuition amounts is known to equal $9,000. At both the 5% and 10% levels...

In a state, 50,000 students graduated from four-year not for profit colleges in 2019. Out of these 50,000 graduates, 20,000 students graduated from private colleges, and 30,000 students graduated from public colleges. You have selected a stratified sample from the population of 2019 graduates in this state with graduates from private and public colleges as the two strata. For each graduate in your sample, you recorded how much student debt, if any, the graduate carried at graduation. The results are...
