The participants were weighted before participating in the program. After the participants went through the weight loss program they were weighed again to see if the weight had decreased. Below is the data of the results. Data given: 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.

VIDEO LECTURES Twо independent grоups оf students were selected to pаrticipаte in а study to determine if having video lectures in an online class has an effect on test scores. The students were randomly (SRS) placed into 2 groups, one group was the online class of 30 students with video lectures and the other group was the online class of 33 students without video lectures. The average test score on the online class of 30 students with video lectures was x-bar: 87 with a standard deviation of s = 1.8 and the average test score the online class of 33 students without video lectures x-bar = 86 with a standard deviation of s = 3.2. Is there enough evidence at the 1% level that the test scores of the online class with video lectures are higher than the test scores of the online class without video lectures? State the conclusion:
