Question 5 (1 point) A study reveals that 65% of homeowners in Omaha own a lawn mower. To test this claim, you form a sample of 500 homeowners in Omaha, of which, 68% owned a lawnmower. Is there enough evidence to reject the claim using a level of significance of 5%? Enter the Null Hypothesis for this test: HO: Enter the Alternative Hypothesis for this test: H1: Is the original claim in the Null Hypothesis (HO) or the Alternative Hypothesis...

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H when the level of significance is (a) a= 0.01, (b) a 0.05, and (c) a0.10. P 0.0749 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H because the P-value, 0.0749, is greater than a=0.01 O B. Fail to reject Ho because the P-value, 0.0749, is less than a = 0.01 O C. Reject...
(1 point) (For the following question, you may use the "hand calculations" described in lecture. You must use at least four decimal places for all intermediate calculations and your final answer. If you use R prop.test(), remember to convert the X2 value to a Z value for your answer!) Independent random samples, each containing 80 observations, were selected from two populations. The samples from populations 1 and 2 produced 59 and 54 successes, respectively. Test Ho : (P1 – P2)...

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject He when the level of significance is (a) a = 0.01, (b) a = 0.05, and (C) a = 0.10. P = 0.0695 (a) Do you reject or fail to reject He at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0695, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0695,...
