The mean number of sick days an employee takes per year is believed to be about ten.Members of a personnel department do not believe this figure. They randomly survey eightemployees. The number of sick days they took for the past year are as follows: 12; 4; 15; 3; 11; 8;6; 8. Let x = the number of sick days they took for the past year. Should the personnel teambelieve that the mean number is ten with a level of significance of 5%?f) State your null and alternative hypothesisg) Choose the appropriate test statistich) Critical values and corresponding critical regioni) Compute the test statisticj) Decision and conclusion

PCB contamination of a river by a manufacturer is being measured by the amount of the pollutant found in fish. A company scientist claims that the fish contain only 5 parts per million, but an investigator believes the figure to be higher. A sample of 6 fish are collected and the PCB measured. Is there evidence at the 0.05 significance level that the investigator’s claim is correct? 6.8, 5.6, 5.2, 4.7, 6.3, 5.4
An epidemiologist found five cases of “big toe cancer” in the Yukon Territory. Because there were only a few cases, the epidemiologist decided to conduct a matched case-control study to determine whether shoe size larger than 9 is a risk factor for big toe cancer. Cases were individually matched to one control for daily activity, history of athlete’s foot, and history of ingrown toenails. The following data were gathered: Shoe size > 9 Pair Case Control 1 Yes No 2 No No 3 No Yes 4 Yes Yes 5 No Yes Compute the proper measure of association. Interpret your results. If you were to investigate a rare cancer in Lynchburg, where might you look for data? What would be necessary legally and ethically to be able to utilize this data set(s)?

The UWI student association published an evaluation of the courses taught during Semester 1 of AY2020/21. Students in each course completed an evaluation in which they rated a number of different aspects of the course on a 5-point scale (1= very bad to 5=excellent)” Five variables obtained are: Rating – overall rating of the CC – rating of teaching skills of the assessments – quality of assessments given knowledge – rating of the instructor’s knowledge of the material grade - student’s anticipated grade for the course (1=F to 5=A) Rating CC Assessments Knowledge Grade 4.5 3.4 3.9 2.9 4.5 2.8 4.1 3.2 3.8 3.7 3.9 4.5 3.0 3.2 3.8 5.0 4.8 3.9 3.9 3.4 1.8 3.1 1.2 2.8 2.7 3.4 2.5 4.0 3.6 4.2 4.7 4.7 4.0 3.2 3.8 2.2 3.8 2.8 2.7 4.5 3.8 4.4 4.5 3.9 4.7 4.6 4.5 4.7 4.6 4.1 3.2 2.7 3.1 3.2 3.8 3.1 3.9 4.4 3.3 3.5 4.8 4.6…
