A B с D A study wanted to see if people's weight changed on a new drug. They weighed 6 people before and after the trial. The six before weights were 150, 160, 175, 162, 180, 240. The respective after weights are 142, 171, 162, 142, 171, 235. A study wanted to know if a new drug was affected weight differently then a drug in a previous study. In the previous study, the participants lost 15 pounds on average. In the new study, they sampled 60 people. The average weight lost was 18 pounds with a standard deviation of 9 pounds. A study wanted to compare the weight loss between two drugs. They sampled 60 people. 30 who took drug A and 30 who took drug B. With drug A the average weight loss was 15 pounds with a standard deviation of 8 pounds. With drug B the average weight loss was 18 pounds with a standard deviation of 9 pounds. A study wanted to compare the percentage of a certain town who planned to vote for candidate A to the national estimate of 72% to see if the percentage in the town was different then the known national estimate. Of the 200 people sampled, 68% planned to vote for candidate A.
