Note: assume the population variances are equal. Exercise 6
Generate S = 1000 random samples of size n = 16 from a normal distribution with mean of
10 and standard deviation of 2.
For each of the s ∈ {1, . . . , 1000} datasets, compute the sample mean x.

Make a histogram for the 1000 values of x.
¯
What is the proportion of values of x (among the 1000 samples) that are greater than 11?
