According to a recent poll, 27% of Americans get 30 minutes of exercise at least five days each week. Let's assume this is the parameter value for the population. You take a simple random sample of 25 Americans and let p(hat) equal the proportion in the sample who get 30 minutes of exercise at least five days per week. Does the sampling distribution pass the Normal condition? 1) Yes because n >= 30 2) No, because n < 30 3) Cannot be determined 4) No, because np < 10 5) Yes, because n (1-p) >= 10
Suppose that you enter a fantasy baseball league. Suppose that the 2021 team budget, say , is randomly drawn from a uniform distribution on the interval , where the unit is U.S. million dollars. In addition, suppose that after the value has been observed , the 2022 team budget, say , is randomly drawn from a uniform distribution on the interval . In other words, the 2022 budget is at most as large as the 2021 budget. a) For any given value of x(50<x<350), obtain E[Y|X=x] b) In view of part (a), obtain E[Y|X] c) Atlanta Braves won the 2021 World Series title.
