1. describe the distribution of sample means (shape, Expected value, and standard error) for samples of n=36 chosen from the population with mean of m =100 and standard deviation of s=12.
2. For population with mean of m =50 and standard deviation of s =10. How much error, on average, would you expect between sample mean (M) and the
population mean for:
a. a sample of n=4 scores.
b. a sample of n=16 scores.
c. a sample of n=25 scores
