These two groups are two samples representing the population of
workers in the economy. We want to know if the workers who take the
training (treatment sample) have higher earnings than the group
that do not take the training (control sample). If we find that the
trained workers have higher earnings it would indicate that the
training is effective.[1]In terms of statistics, we will do a
hypothesis test on the difference between the mean earnings in the
treatment population and...

A workshop is designed to help students prepare for college algebra, and we want to evaluate its effectiveness. There are 10 college students with similar math skills selected in the study. The student take a test before they attend the workshop, then after they attend the workshop, they will take another test with the similar difficulty level. The data are collected and summarized as below. Perform an appropriate statistical inference to answer the research questions. Mean Standard Deviation Min Max...

Question 5 (1 point) It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test the hypothesis that students who study one week before score less than students who study the night before. A hypothesis test for two independent samples is run based on your data and a p-value is calculated to be 2e-04. What is the appropriate conclusion? 1)...
