Suppose that you are doing the following hypothesis test: H 0

:μ=μ 0

=42;H 1

:μ<μ 0

=42. Assume a significance level of α=0.025. Find the critical value for the decision if the population standard deviation is 2 and a random sample of 100 is drawn. (Remember to pick the closest answer.) A. 41.6 B. 41.8 C. 42 D. 42.2 E. 42.4 42−1.96∗ 100

2

=42−1.96∗0.2≈41.6
