- Natasha is a physician looking to determine whether a supplement is effective in helping men lose weight. She takes a random sample of overweight men and records their weights before the trial. Natasha then prescribes the supplement and instructs them to take it for four weeks while making no other lifestyle changes. After the four-week period, she records the weights of the men again. Suppose that the data were collected for a random sample of 6 men, where each difference is calculated by subtracting the weight before the trial from the weight after the trial. Assume that the populations are normally distributed. The test statistic is t≈−2.795, α=0.05, the corresponding rejection region is t<−2.015, the null hypothesis is H0:μd=0, and the alternative hypothesis is Ha:μd<0. Which of the following statements are accurate for this hypothesis test in order to evaluate the claim that the true mean difference between the weight of men after the trial and the weight before the trial is…A psychologist would like to examine the effects of a new drug on the activity level of animals. Three samples of rats are selected with n = 5 in each sample. The rats in the first sample serve as a control and do not get any of the drug. The rats in the second group receive a small dose, and the rats in the third group each get a large dose of the drug. The psychologist records the activity level for each animal. The data from this experiment are presented below. no drug small dose large dose 2201O 22321 Complete the F-ratio table below.

- In a large ball pit, 20% of the balls are red. You plan to jump in and randomly select 10 balls. Which statement is true? You are guaranteed to have exactly two red balls in your sample. You will likely have one to three red balls in your sample. You will most likely have eight red balls in your sample. It is unlikely that you will have exactly two red balls in your sample.Researchers want to investigate whether taking aspirin regularly reduces the risk of heart attack. Four hundred men between the ages of 50 and 84 are recruited as participants. The men are divided randomly into two groups: one group will take aspirin, and the other group will take a placebo. Each man takes one pill each day for three years, but he does not know whether he is taking aspirin or the placebo. At the end of the study, researchers count the number of men in each group who have had heart attacks. Identify the following values for this study: population, sample, experimental units, explanatory variable, response variable, treatments.
