Determine the answers of the following questions: A clinic provides a program to help their clients lose weight and asks a consumer agency to investigate the effectiveness of the program. The agency takes a sample of 15 people, weighing each person in the sample before the program begins and 3 months later to produce the table below. Determine whether the program is effective. The information collected was encoded in MS Excel. Using data analysis, the following values are generated: 1. What is the critical value? 2. What is the test statistic/computed value? 3. What is the decision?
