Section IV. C. Questions A random sample of 15 monthly rents for two-bedroom apartments was selected from a certain city. The mean of this sample is $636. Assume the population standard deviation is $121. A group of students think the mean rent for two-bedroom apartments is less than $650. Test their claim with a significance level of a 0.05. Use this scenario to answer questions 1-5. 1) State the alternative and null hypothesis. 2) Calculate the test statistic
