Prof. B Santanu wanted to study if brightest students (getting high scores) submit answer-sheets in exam hall earlier (as they recall lessons well) or later (for, they may write all in minute detail), than others. In last QT test, Professor noted the order of submission, and their score (marks). One scores 90 or above, is considered as 'brightest student'. Test (at 5% level), based on following data, if we can conclude that, brightest students submit answer-sheets randomly'.

Elaine is interested in determining if men are more satisfied in their jobs than women in the healthcare industry. She administers a job satisfaction questionnaire to 20 men and 20 women working in hospital administration. Her grouping variable is gender and dependent variable is job satisfaction. The job satisfaction scale consists of 8 items measured using a 5-point rating scale. A higher score on this scale would indicate high job satisfaction. The maximum score that can be obtained on the scale is 40. We can assume that job satisfaction scores are normally distributed. Use the appropriate T test with a significance level of 0.05 to test the hypothesis. Research Question Do the mean job satisfaction scores differ for men and women working in the hospital administration department? Hypothesis The mean job satisfaction scores do not differ for men and women working in the hospital administration department. Compute an independent sample t test on these data. Report…

Hi there, I hope you’re well. We have a research report/proposal due for Statistics next month. We were told to gather data on anything related to schools, learners or teachers. I have chosen to gather data on academic achievement and sports participation. I am interested in the difference between a learners academic achievement and whether he/she takes part in sports or not. I received data from the school which I put into a table. It is the academic term average for those who do sports and those who do not. We are now required to carry out two tests along with graphs etc. I have done the t-test and am happy with the results. I would like to do a chi-square test as my second test, but I am completely lost. I have my raw data (please see attached) but I am struggling to move forward. I need to find out what the observed and expected data is (from my raw data) and carry out the test. Please could you assist me. I would really love to do well in this course, but it is not my strongest…
