A study suggests that the average college student spends 20 hours per week preparing for classes. Your research team believes this claim is an overestimate and decides to collect their sample for a hypothesis test. a) Fill in the missing value in the null hypothesis below: H0 : u0 = b) write out your teams' alternative hypothesis in notation form: H1: c) your team randomly recruits 35 students for your study. Based on this sample size, should you use z or t-test statistics for your hypothesis test? Explain your reasoning? d) write out the decision rule for your hypothesis test. Make sure to include the appropriate z or t critical value. You may assume a 5% significant level e) on average, your team found that the 35 subjects in your sample spent 15.8 hours a week preparing for classes with a standard deviation of 8.9 hours. use this information to calculate the appropriate test statistics. f) make a decision using the decision rule in (d) and the calculated test statistics in (e). Write out an appropriate conclusion
