a. Show calculations for the mean and standard deviation of the sampling distribution for x-bar for the sample of 100 students.
b. Calculate the probability that when I take the random sample of 100 students I find an x-bar greater than 70. That is calculate P(x-bar >70).
c. Calculate P(x-bar 55) for this sample of 100 students.
d. If SMSUs continued funding from the state government depended on finding that more than 50% of students could pass a statistics test with a score of 60 or more, wo
