A random sample of 12 second-year university students enrolled in a business statistics course was drawn. At the course's completion, each student was asked how many hours he or she spent doing homework in statistics. The data are listed below Assume it is known that the population standard deviation is α=10. The instructor has recommended that students devote 5 hours per week for the duration of the 12 -week semester, for a total of 60 hours. Test to determine whether there is evidence at the α=0.02 significance level to concluce the average student spent less than the recommended amount of time. (a) Set up the null and altemate fypothesis for this problem Note: Use u for the mean μ,​⟨>for ϕ,<= for ≤,>⇒ for ≥ and state μ0​ as an integer value with no decimal places H0​ : Use a non-directional null hypothesis like μ=μ0​ even if the problem is right or left tailed. H1​: (b) Find the value of the standardized test statistic: Note: For the next part, your answer should use interval notation. An answer of the form (−∞,a) is expressed (−inf, a), an answer of the form (b,∞) is expressed (b, inf), and adtinnswer of the form (−∞,a)∪(b,∞) is expressed (-inf, a) (b. inf) (c) The rejection region for the standardized test statistic: (d) The p-value is Now you can either use parts A and B and the test statistic method to determine whether or not to reject H0​ or you can use part C and compare the p-value to the significance level to determine whether or not to reject H0​ (e) Your decision for the hypothesis test. A. Fail to Reject H0​ - the students appear to be studying the recommended amount. B. Reject H3​ - the students appear to be studying less than the recommended amount c. Reject H0​ - the students appear to be studying less than the recommended amount. D. Fail to Retect H1​ - the students appear to be studying the recommended amount.
