Because of the Rising Costs of Industrial Accidents, Many Chemical

Short Answer

Because of the rising costs of industrial accidents, many chemical, mining, and manufacturing firms have instituted safety courses. Employees are encouraged to take these courses designed to heighten safety awareness. A company is trying to decide which one of two courses to institute. To help make a decision, eight employees take course 1 and another eight take course 2. Each employee writes a test, which is marked, out of a possible 25. The results are shown below. Do these data provide sufficient evidence at the 5% level of significance to conclude that the marks from course 2 are higher than those of course 1? Assume that the scores are not normally distributed.
The null and alternate hypotheses are: : The two population locations are the same. : The location of population 1 (course 1) is to the left of the location of population 2.
Test statistic = ______________
Critical Value = ______________
Conclusion: ______________
There ______________ enough evidence to include conclude that the two populations are the same.
