STA 210 - Homework 12 Section IV. C. and Lab 12 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 fucfir claim with a significance level of a = 005. Use this scenario to answer questions 1-5. 1) State the alternative and null hypothesis. 2) Calculate the test statistic. 3) Identify the p-value. 4) Make your decision 5) Interpret the results. A book about college reports that the mean time students study each week is 1015 minines. A dean says she believes the mean is greater than 1015 minutes. Suppose she takes a random sample of 64 students and finds that the sample mean is 1050 minutes. Assume the population standard deviation is 150 minutes. Test the deans claim at a = 0.05. Use this scenario to answer questions 6-10. 6) State the alternative and null hypothesis. 7) Calculate the test statistic. 8) Identify the p-value. 9) Make your decision. 10) Interpret the results
