Let Y1 and Y, be two independent observations from a Poison distribution with parameter A> 0. Consider the statistic T = Y +2Y½, Evaluate P{Y1 = 0, Y2 = 1|Y1 +2Y2 = 2} . Using Definition 9.3 (and only Definition 9.3), is T sufficient for A > 0 (explain why yes or why no)? Let Y1, Y2, .., Y, denote a random sample from a probability distribution with unknown parameter 0. Then the statistic U = g(Y1, Y2,., Y,) is said to be sufficient for 0 if the conditional distribution of Y1, Y2, ..., Yn, given U , does not depend on . ....

Suppose a linear model y=β0+β1xy=β0+β1x is fit to a sample data set, and a test of the null hypothesis H0:β1=0H0:β1=0 against an alternative hypothesis HA:β1≠0HA:β1≠0 is performed; a PP-value of 0.4203 is obtained.

A dietitian wishes to see if a person’s cholesterol level will be changed if the diet is supplemented by a certain mineral. Four subjects were pre-tested, and they took the mineral supplement for a 6-week period. The results are shown in the table. Is there sufficient evidence to conclude that the population mean of cholesterol levels has been changed after six weeks at α=0.2α=0.2? Assume that the differences are from an approximately normally distributed population.
