An organizational psychologist was asked to test a claim by a franchise swimming instruction program. Specifically, the franchisers claimed that they could teach the average 7-year-old to swim across an Olympic-size pool in less than 2 hours. The psychologist arranged for eight randomly selected 7-year-old children to take instruction at this school and kept a record of how long it took each child to swim across the pool. The times (in minutes) were 60, 120, 110, 80, 70, 90, 100, and 130.

Following attest for a single sample (120 minutes is the "known" population mean) using the .01 significance level, what should the psychologist conclude?

a. Use the five steps of hypothesis testing.
