You have a set of normally distributed scores with a mean of 16 and a standard deviation of 3 (= 16,= 3).

Nowsuppose 200 persons received scores during a period of a week. How many would have scores of 15 or smaller (X=15)?

Given , a population with a mean()of 10 and a standard deviation () of 1 andIfthe sample size is 3 (N= 3),

1.) what proportion of the means of a sampling distribution would be larger than 12?

2.) what proportion of the means of a sampling distribution would be smaller than 9?

If you could please help me get a better understanding of these problems, thank you!
