MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You may need to use the appropriate appendix table or technology to answer this question. In a study entitled How Undergraduate Students Use Credit Cards, it was reported that undergraduate students have a mean credit card balance of $3,173. This figure was an all-time high and had increased 44% over the previous five years. 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 original report. Based on previous studies, use a population standard deviation o = $1,000. (a) State the null and alternative hypotheses. Ho: M 3,173 Ho: M > 3,173 Ha: M S 3,173 Oho: M = 3,173 Ha: M # 3,173 (b) What is the test statistic for a sample of 170 undergraduate students with a sample mean credit card balance of $3,355?
