2. A swimming school claimed that the average seven-year-old would be able to swim across an Olympic-sized pool in less than 2 minutes (120 seconds) after taking lessons from their instructors. To test this claim, a consumer psychologist arranged for eight randomly selected seven-year-old children to take lessons at the school and recorded how long it took each child to swim across a pool at the end of the lessons. The times (in seconds) were 60, 120, 110, 80, 70, 90, 100, and 130. What conclusion would the psychologist draw following at test for a single sample using 120 seconds as the "known" population mean and the .05 significance level? Use the five steps of hypothesis testing and calculate effect size. Note that I gave you scores instead of Sum of Squares (SS). You will have to calculate this yourself.
