Patient Weight before Weight loss program Weight after Weight loss program A 150 148 B 220 221 C 175 170 D 200 200 E 300 295 F 290 293 G 285 282 H 195 194 I 295 292 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
