In this week's problem, I interviewed my cycling group to see how many have participated in a Triathlon. I hypothesized that the population mean number of people who participated is 4, and my random sample results were: 2,7,3,2,3,0,0. I am choosing to test this hypothesis at the 0.15 significance level.

    Based on anecdotal evidence (i.e., nonrandom, small samples), some have hypothesized that IQ scores have actually improved among recent birth cohorts. When a particular IQ test was validated in the 1990s, the mean was 100, with a standard deviation of 15. Suppose I hypothesize that current IQ now has a population mean of 110 (with a standard deviation of 15). I take a random sample of 20 people and find mean is 105. What can I say about my hypothesis?
