A researcher conducts a study examining the effectiveness of a group exercise program at an assisted living facility for elderly adults. One group of residents is selected to participate in the program, and a second group serves as a control. After 12 weeks, the researcher records a combined score measuring balance and strength for each individual. The data are as follows: Control n = 20 M = 24 SS = 241 Exercise n = 30 M = 31 SS = 380 a. Use a two-tailed test with a = 0.1. Conduct the four steps for hypothesis testing and label each step: Step1, Step 2, Step 3, and Step 4.
