Grade distribution guidelines for a statistics course are: 25% A's, 40% B's, 20% C's, 10% D's, and 5% Fs. A sample of 120 statistics grades at the end of the Winter semester showed 32 A's, 38 B's, 40 C's, 7 D's and 3 F's. Use a 5% significance level to test whether the actual grades deviate significantly from the expected grade distribution guidelines. What is the correct decision rule for this problem? Multiple Choice Reject HO, if computed chi-sqaure value...

5. One year, the A's play the B's in the World Series, a seven-game series of baseball games. The World Series winner is the team that wins at least four games.1 Suppose that all games are independent and for each game, the probability that the A's win is p (which is the same for each game.) We don't know the exact value of p, but it's estimated that in professional baseball, the better team wins between 50% and 70%...
