An industrial-organizational psychologist claims that partners will recognize the satisfied customer in less than 2 minutes after taking computerized lessons. To test this claim, eight randomly selected partners took lessons and recorded how long it took to find one. The times (in seconds) were 60, 120, 110, 80, 70, 90, 100, and 130. The SS turned out to be 4,200. • What conclusion would be found for a t test for a single sample using 120 seconds as the "known" population mean and the .05 significance level? • Please use the 5 steps of hypothesis testing. • Sketch the distributions for steps 3 & 4.
