Question

A psychologist would like to examine the effects of hours of sleep on performing problem solving tasks. The data from this experiment are presented below. She looks at how much time (in minutes) people take to solve a complex problem solving task after being exposed to either 8-10 hours of sleep, 7 hours of sleep, or less than 7 hours of sleep. Do these data indicate any significant differences among the three sleep groups? If so, what are they? Perform analyses by hand, but feel free to check your work using SPSS. Write up your conclusion in APA format. Test with α = .05.

8-10	7	<7
