Simulate the creation of 10,000 samples of size n (n = your answer to 2 (e)). Where each sample is drawing from a distribution with µ = 81 (tutoring raises scores by one point) and σ = 5 (standard deviation is unaffected by tutoring). • Check whether approximately 90% of the samples are above the critical value for rejecting H0 with α = .05
