PE & SELF-ESTEEM 4 of 4 What is your statistical decision? A researcher is evaluating the effectiveness of a new physical education program for elementary school children. The program is designed to reduce competition and increase individual self-esteem. A sample of n = 35 children is selected and the children are placed in the new program. After 3 months, each child is given a standardized self-esteem test. Her sample received a sample mean of 41. For the general population of elementary school students, the self-esteem test has a population mean of 40 and a population standard deviation of 5. What is your statistical decision?
