8:05 55 Exit 7. In a sample of 150 men, 135 said that they had less leisure time today than they had 10 years ago. In a random sample of 250 women, 239 women said that they had less leisure time than they had 10 years ago. At a = 0.10, is there a difference in the proportions? There is enough evidence to support the claim that the proportions are different because the test value -2.77 is outside the noncritical region -1.65

In a random sample of 250 women, 239 women said that they had less leisure time than they had 10 years ago. At a = 0.10, is there a difference in the proportions? There is enough evidence to support the claim that the proportions are different because the test value -2.77 is outside the noncritical region -1.65 <z< 1.65 There is not enough evidence to support the claim that the proportions are different because the test value -1.56 is inside the noncritical region -1.65 < z< 1.65 There is not enough evidence to support the claim that the proportions are different because the test value -1.25 is inside the noncritical region -1.65 <z < 1.65
