Question 9 3 pts For this problem it would be helpful to have a standard normal table. What is the Z-value needed for the critical value for a one-tailed upper hypothesis test of a proportion with a sample size of 365 and alpha equal to 10? 1.28 2.33 1.645 O 1.96 Question 10 3 pts For this problem it would be helpful to have a standard normal table. What is the z-value needed for the critical value for a one-tailed upper hypothesis test of a proportion with a sample size of 450 and alpha equal to .05? 1.28 1.645 OOO 1.96 2.33

Answer 1

9)

$\alpha$ = 0.10

Z _0.10 = 1.28

Critical value = 1.28

10)

$\alpha$ = 0.05

Z _0.05 = 1.645

Critical value = 1.645
