Please Help! Need to confirm my answer. You wish to test the claim that the average IQ score is less than 100 at the .01 significance level. You determine the hypotheses are: Ho: μ = 100 H1: μ < 100 You take a simple random sample of 100 individuals and find the mean IQ score is 95.7, with a standard deviation of 16. Let's consider testing this hypothesis two ways: once with assuming the population standard deviation is not known...
