Blood sugar readings are normally distributed with a mean of 100 and a standard deviation of 28. Suppose a sample of 196 people is randomly selected. Note: This is a sample mean situation.

a) (2 points) What is the sample mean?

b) (2 points) What is the sample standard deviation?

c) (3 points) What is the probability that the blood sugar sample mean is between 97 and 103?

d) (2 points) Compute the 33th percentile of the blood pressure sample mean.
