A psychologist wants to test whether there is any difference in puzzle-solving abilities between boys and girls. Independent samples of 11 boys and 13 girls were chosen at random. The boys took a mean of 42 minutes to solve a certain puzzle with a standard deviation of 5 minutes. The girls took a mean of 43 minutes to solve the same puzzle with a standard deviation of 3 minutes. Assume that the two populations of...
