We want to determine whether jars of peanut butter have at least 12 ounces in them. The null hypothesis is that the mean is greater than or equal to 12. The alternate hypothesis is that the mean is less than 12. Thirtyone jars of peanut butter are tested. The test statistic is found to be 1.5. What is the p-value for this test?

A psychologist wants to test whether there is any difference in puzzle-solving abilities between boys and girls. Independent samples of twelve boys and ten girls were chosen at random. The boys took a mean of 42 minutes to solve a certain puzzle, with a standard deviation of 4.8 minutes. The girls took a mean of 37 minutes to solve the same puzzle, with a standard deviation of 5.9 minutes. Assume that the two populations of completion times are normally distributed,...
