Question
Chapter 8, Problem 3LC
(a)
To determine
Discuss the statement that “When we fail to reject the null hypothesis, we do not claim that it is absolutely true. We simply claim that at the given level of significance, the data were not sufficient to reject the null hypothesis”.
(b)
To determine
Discuss the statement that “When we accept the alternative hypothesis, we do not claim that the null hypothesis is absolutely false. We do claim that at the given level of significance, the data presented enough evidence to reject the null hypothesis”.

A person's lean body weight L is the amount he or she would weigh if all body fat were magically to disappear. One text gives the "equation that practitioners can use most feasibly in the field to predict lean body weight in young adult males." The equation is found below. L = 98.42 + 1.08W − 4.14A Here L is lean body weight in pounds, W is weight in pounds, and A is abdominal circumference in inches.
