Question 29 In a random sample of 40 Kentuckians, 15 support legal ownership of an alligator. In a random sample of 50 Mississippians, 49 support legal ownership of an alligator. We want to test the claim that the proportion of all Kentuckians is less than the proportion of all Mississippians who support legal alligator ownership. What is the test statistic (z value) for this hypothesis test? Round your answer to 2 decimal places. Add your answer

Question 30 In a random sample of 40 Kentuckians, 15 support legal ownership of an alligator. In a random sample of 50 Mississippians, 49 support legal ownership of an alligator. We want to test the claim that the proportion of all Kentuckians is less than the proportion of all Mississippians who support legal alligator ownership. What is the conclusion of this hypothesis test at the alpha 0.05 significance level? Fail to reject the null hypothesis. We do not have enough evidence to conclude that the proportion of all Kentuckians is less than the proportion of all Mississippians who support legal alligator ownership. B Fail to reject the null hypothesis. The proportion of all Kentuckians is less than the proportion of all Mississippians who support legal alligator ownership. Reject the null hypothesis. We do not have enough evidence to conclude that the proportion of all Kentuckians is less than the proportion of all Mississippians who support legal alligator ownership. Reject the null hypothesis. The proportion of all Kentucklans is less than the proportion of all Mississippians who support legal alligator ownership.

Question 33 For a sample of 42 babies, the gestation length (in weeks) and the baby's weight (in kilograms) were recorded. The linear regression equation for this scatterplot is, fat content (in grams) and number of calories were recorded. The regression equation for this scatterplot is y-0.16% - 3.03 Interpret the slope of this regression equation in the context of the problem. For each additional kilogram of birthweight, a baby tends to have 3.03 fewer weeks of gestation B For each additional kilogram of birthweight, a baby tends to have 0.16 more weeks of gestation. For each additional week of gestation, a baby tends to weigh 0.16 more kilograms on average. For each additional week of gestation, a baby tends to weigh 3.03 less kilograms on average.
