A study on student success in college examines whether mandatory mentoring in the first year of college reduces anxiety experienced by students. To address this question 150 students are randomly selected to participate in a mentoring program their first year of college. These 150 students are given a questionnaire and anxiety is measured on a 1-20 scale where 1 is the most anxiety and 20 is the least anxiety. This sample is compared to the known anxiety for students who don’t receive mentoring. Anxiety in the population is known to be positively skewed, with a mean of 12 and a standard deviation of 2.

in comparing the engagement levels of first-year statistics students. In a previous nation-wide study, engagement levels were found to be normally distributed, with µ=60.00, σ=10.00. The lecturer collects a convenience sample of 50 first-year students and finds that her students have a mean engagement level equal to 75.54. What statistical procedure should be used, to test whether there is a significant mean difference in engagement levels between the lecturer’s first year students and the population average? a. One sample Z-test....

(16.19) A class survey in a large class for first-year college students asked, About how many hours do you study during a typical week? The mean response of the 463 students was x = 15.3 hours. Suppose that we know that the study time follows a Normal distribution with standard deviation σ = 8.5 hours in the population of all first-year students at this university. Step 1: Use the survey result to give a 99% confidence interval for the mean...

Victoria Snelgrove was a 21-year-old college student who was shot and killed with a police projectile after the Boston Red Sox beat the Yankees in the American League Championship Series. Following the incident, you take a random sample of 144 criminal justice students here at university and ask them to rate their level of outrage over police use of force in this case. On a scale from 1 to 10, respondents rate their outrage at 7.8. The average level of...

The subjects in the data are college students. In the data, id is student ID, anxiety is student’s anxiety score via Anxiety Scale, selfest is student’s self-esteem score via Rosenberg Self-esteem Scale, GPA is student’s GPA; for gender, 0=female, 1=male; for grade, 1=freshman, 2=junior, 3=senior. We have known that population mean for Anxiety Scale is μ=60 with σ=10. Raise relevant questions ( 2 questions is fine) about the data extensively, the questions can be either about descriptive analysis or inferential...
