Previous 2 4 15 6 89 10 Next Question 3 of 11 (1 point) View problem in a pop-up Use Table A.3 to find the critical value or values for the following values of the significance level a, sample size n, and alternate hypothesis H1- 8.3 Section Exercise 13-14 Part 1 when α = 0.01, n = 20, and HI: μ > μ 0. t- 2.023 Correct answer: 2.539 Part 2 out of 4 when α = 0.10, n = 13, and HI : μ 〈 μ0.

Answer 1

Using the tables, at alpha =0.01, n=20critical value for t test is at tn-1 ie at t19 so critical value is 2.539

For n=13 and alpha =0.1, critical value is at t12 and 10% so it is 1.356
