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.

Which of the following is/are FALSE about the central limit theorem? A. The CLT says that as the sample size nn increases to infinity, the sample mean converges to the population mean, given that the population mean and variance are finite. B. The CLT explains why the binomial distribution will approximately be normally distributed when nn is large. C. The CLT says that at a large sample size nn, the sample mean will be approximately normal with mean equal to the population mean and variance equal to the population variance divided by the sample size nn , given that the population mean and variance are finite.

In bacterial counts with a haemacytometer, the number of bacteria per quadrat has a Poisson distribution with probability mass function f(x), where f(x) = θ x e −θ/x! and θ is to be estimated. If there are many bacteria in a quadrat, it is difficult to count them all, and so the only information recorded is that the number of bacteria exceeds a certain limit c, a large positive integer. In a random sample of n quadrats, it was.
