1.For a population with a mean of 75 and a standard deviation of 12, what proportion of sample means of size n = 16 fall above 82?

2.For a population with a mean of 100 and standard deviation of 16, what is the probability that a random sample of size 4 will have a mean between 110 and 130?

3.Find the z-score for the following means taken from a population with mean 10 and standard deviation 2: a. X = 8, n = 12 b. X = 8, n = 30 c. X = 20, n = 4 d. X = 20, n = 16

5.For a population with a mean of 35 and standard deviation of 7, find the sample mean
