In a study entitled How Undergraduate Students Use Credit Cards, it was reported that undergraduate students have a mean credit card balance of $3173 (Sallie Mae, April 2009). This figure was an all-time high. Assume that a current study is being conducted to determine if it can be concluded that the mean credit card balance for undergraduate students has continued to increase compared to the April 2009 report. Based on previous studies, use a population standard deviation σ= $1000. State...

In a study entitled How Undergraduate Students Use Credit Cards, Sallie Mae reported that undergraduate students have a mean credit card balance of $3173. This figure was an all-time high and had increased drastically over the previous five years. Assume that a current study is being conducted to determine whether it can be concluded that the mean credit card balance for undergraduate students has continued to increase compared to the April 2009 report (i.e. greater than 3173).

Many students graduate from college deeply in debt from student loans, credit cards, and so on. Curious about the impact of debt on decisions about the future, a WCU sociologist took a random sample of 401 single students at WCU, classified them by a binary view of gender, and asked, “Would you consider marrying someone who was $25,000 or more in debt?” The results of this survey are shown in the following table. Test at a 1% significance level if...

The time needed for college students to complete a certain puzzle is modelled using a normal distribution with a mean of 30 seconds and a standard deviation of 3 seconds. You wish to see if the population mean time µ is changed by vigorous exercise, so you have a group of nine college students exercise vigorously for 30 minutes and then complete the puzzle. What is the rejection region at the significance level 0.01? What is the power of the...

In 2015, the Nellie Mae organization conducted an extensive study of how college students used credit cards. Two of their goals were to estimate the percentage of college students that have a credit card and the average credit card balance. To do this they randomly selected data for 600 undergraduate students aged 18-24 attending four-year public and private colleges across the United States who had applied for a loan with Nellie Mae during the summer and fall of 2001. a)...
