Assume that the heights of 3500 female students at a university are normally distributed with mean 67.0 inches and standard deviation of 3.0 inches. If 80 samples consisting of 25 students are obtained, What are the expected mean and standard deviation of the resulting sampling distribution of means if sampling were done with replacement?

Assume that the heights of 3000 male students at a university are normally distributed with mean 68.0 inches and a standard deviation of 3.0 inches. If 80 samples consisting of 25 students each are obtained, what would be the mean and standard deviation of the resulting sample of means if sampling were done (a) with replacement, (b) without replacement?

Assume that the heights of 30,000 male students at a university are normally distributed with a mean of 68.0 inches and a standard deviation of 3.0 inches. A random sample of 35 students is taken and the mean is calculated. What is the probability that this mean value will be between 66.8 inches and 68.8 inches?
Assume that the heights of 6000 male students at a university are normally distributed with mean 64.0 inches and standard deviation 2.7 inches. If a random sample of 81 students are selected with replacement, What is the probability that the average height in the sample will be between 63.34 and 64.45 inches?
