(a) What are the null hypothesis and alternate or research hypothesis that you would state in order to assess the effectiveness of the course in deterring acceptability of academic offences?

(b) What sampling distribution would you use, and what formula(s) would you use?

(c) Given an alpha level of 0.05, what is the critical value of the test statistic?

(d) If the value of the obtained test statistic is +1.754, what would you conclude about the effectiveness of the course? Be sure to state the conclusion in statistical terms, and in words.

The university is concerned about a rise in the number of academic offences committed by undergraduate students. They believe that students do not understand the seriousness of such offences. They develop a course that outlines the potential consequences for students who are involved in academic offenses (e.g. cheating, plagiarism, etc.) in order to deter students’ acceptability of committing these offenses. All first year students are required to take the course. To assess the effectiveness of the course in deterring (or reducing) acceptability of academic offences, before the course starts, a random sample of 150 first year students are asked to complete a questionnaire that includes a scale to assess their views on the acceptability of committing an academic offence. After the course is over, a different sample of 156 first year students complete the same questionnaire. Scores on the scale range from 0 to 25 (interval/ratio measure), with a mean (X") and standard deviation (s) determined for the scores in each sample. Higher scores reflect GREATER acceptability of academic offences.
