The data below was collected from Math 13 students. They were asked how many units they were taking this semester and to rate their math anxiety level, on a scale from 0 to 10.
For each hypothesis test, provide the claim, critical values, test statistic and conclusion.
1) Test the claim that men and women are taking the same number of units, on average.
2) Test the claim that men and women have the same level of math anxiety, on average.
3) Test the claim that the proportion of people taking over 12 units is the same for men and women.
4) Test the claim that the standard deviation for the number of units taken this semester is the same for men and women.
5) Divide the data into two groups: those with 0-5 math anxiety and those with 6-10 math anxiety. Test the claim that the
average number of units is the same for these two groups.

A study reported in the Journal of Small Business Management concluded that selfemployed individuals do not experience higher job satisfaction than individuals who are not selfemployed. In this study, job satisfaction is measured using 18 items, each of which is rated using a Likerttype scale with 1–5 response options ranging from strong agreement to strong disagreement. A higher score on this scale indicates a higher degree of job satisfaction. The sum of the ratings for the 18 items, ranging from 18 to 90, is used as the measure of job satisfaction. Suppose that this approach was used to measure the job satisfaction for lawyers, physical therapists, cabinetmakers, and systems analysts. The results obtained for a sample of 10 individuals from each profession follow. SatisJob Lawyer Physical Therapist Cabinetmaker Systems Analyst 44 55 54 44 42…arrow_forward

She also designs a questionnaire to measure anti-Arab oppression so she can test the participants' level of anti-Arab oppression before and after the intervention. She tests one version of her questionnaire with 45 statements and a shorter version with 12 statements. In both questionnaires, the participants respond to each statement with a rating on a 5-point Likert scale with 0 equaling "strongly disagree" and 4 equaling "strongly agree." The overall score for each participant is the mean of his or her ratings for the different statements on the questionnaire. Look at the following graphs.
