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.

The sampling distribution of x̄ is: approximately normal if the population is not highly skewed. approximately normal because of the central limit theorem. approximately normal only if the population is normally distributed. approximately normal because x̄ is always approximately normally distributed.5 Which of the below about t-distribution is TRUE? Each curve is more spread out than the standard normal curve. Each t curve is bell shaped and centered at 0. As the degree of freedom decreases, the sequence of t curves approaches the standard normal. All the statements are correct about t-distribution.
