Using Microsoft Excel functions,

Suppose a simple random sample of size 45 is drawn from a population with mean 85 and standard deviation 8.2. Answer the following:

A. What proportion of sample means would be greater than 87? P(X > 87)

B. What proportion of sample means would be between 83 and 87? P(83 < X < 87)

(round answers to nearest hundredth percent – i.e. 34.05%)
