Problem 5 a) Suppose that, in a random sample of 40 accounting students who had their second co-op term in W19, the sample mean and hourly wage and standard deviation were $20.10 and $3.15, respectively. Calculate a 95% confidence interval for the mean hourly wage of all accounting students with a second co-op term in W16. Interpret your interval. b) Suppose that based on historic data accounting students on their first co-op term typically earn an average of $17.84 per...

According to the Institute for Students in Shackles, 70% of all college students in a recent year graduated with student loan debt. The University of Florida reports that only 52% of its graduates from a random sample of 500 students have student loan debt. Use a hypothesis test to determine if there is enough evidence to support UF’s claim that student loan debt is less. a) State your null and alternative hypothesis. b) Find p-hat, SD, Z, and the P-value
