Suppose a researcher wants to evaluate the effect of new diet on weight loss. He randomly selected five subjects and let them use the diet for 6 months, and then compared the weights before and after the diet. Refer to the table below: Patient Weight Before(kg) Weight After(kg) 1 90 86 85 80 86 80 93 95 94 92 Test at a = 0.01 if there was a statistically significant average decrease in weight from before diet treatment to 6 months after.
