Suppose that X1, X2, ..., Xn are iid with a beta (nu,1) distribution and Y1, Y2, ..., Ym are iid beta (theta, 1) distribution. Assume Xs and Ys are independent.
1) FInd a likelihood ratio test of Ho: theta = nu vs. Ha: theta different from nu
2) Show that the test in part A can be based on the statistic
T = (sum of log(Xi))/((sum of log(Xi))+(sum of log(Yi)))
3) Find the distribution of the test statistic when the null hypothesis is true, and then show how to get a test size alpha= 0.10
Ten pairs of points yielded a correlation coefficient y of 0.79. If a=0.05, which of the following statements is correct if H 0:P=0? (Do not calculate a t-value.)
Estimate the population mean
A sample of n=20 has a mean of M=40. If the standard deviation is s=5, would a score of x=55 be considered an extreme value?

Micron Electronics makes both desktop and laptop personal computers that they sell directly to customers by phone or over the Internet.
Consider a normal population with µ = 25 and σ = 7.0. (A) Calculate the standard score for a value x of 23.
The null hypothesis is to be tested at 95% confidence. Determine the critical values for this test.
A final exam in Math 157 is normally distributed and has a mean of 75 with a standard deviation of 12. If 36 students are randomly selected, find the probability that the mean of their test scores is greater than 70.
