In a test of physical fitness, a group of men ages 65 and older from a local retirement community were told to do as many sit-ups as they could. It is known that the population mean μ is 20 with standard deviation σ = 8. The average number of sit ups for men (n=16) from the retirement community was M = 24.5.
