The percent of fat calories that a person in America consumes each day is normally distributed with a mean of about 36 and a standard deviation of about ten. Suppose that 16 individuals are randomly chosen. I am having trouble figuring out these questions.

For a sample of size 16, how would I state the mean of the sample mean.

For a sample of size 16, how do I state the standard deviation of the sample mean (the “standard error of the mean”).

If a sample of size 16 is taken how do I find the probability that the average percent of fat calories consumed is more than 30.
