Question

The GPAs of 11 randomly selected fraternity members and 11 randomly selected non- fraternity students were obtained from the student body. The sample means and standard deviations are given below. Perform a test of hypothesis to determine if there is a difference between the mean GPA of fraternity members and the mean GPA of non-fraternity students. Use alpha = 0.05. WVU has two games ahead. The chance they win the first game is 0.55.ifthey win the first game there will be 0.6 chance to win the second game. If they lose the first game, there will be 0.5 chance of winning the second game. Find the probability that WVU win one game and lose one game.

Explanation / Answer

Probability of WVU wins the first game but loose the second game = P(they loose the 2nd game | they won the first game) . P(they won the first game) = (1-0.6) * 0.55

= 0.4 * 0.55

= 0.122
