Identify the hypotheses being tested: HINT: Small sample, we are testing the DIFFERENCE, We want to know if it is less than when AFTER - BEFORE. Basically we believe the weight loss program lowers the participant’s weight. Improvement means weight went down. Given: level alpha is 0.01. QUESTION: What is the conclusion?

a) We DO reject Ho. There is statistically significant evidence to reject Ho. We conclude the average difference (After - Before program) in weight is less than 0.

b) We DO NOT reject Ho. There is NOT statistically significant evidence to reject Ho. We conclude the average difference (After - Before program) in weight is NOT less than 234.44.

c) We DO NOT reject Ho. There is NOT statistically significant evidence to reject Ho. We conclude the average difference (After - Before program) in weight is NOT less than 0.

d) We DO reject Ho. There is statistically significant evidence to reject Ho. We conclude the average difference (After - Before program) in weight is less than 2.34.44.
