Essay

Employees are encouraged to take these courses, which are 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 takes a test, which is graded out of a possible 25. The safety test results are shown below. $$\begin{array} { | l | l | l | l | l | l | l | l | l | } \hline \text { Course 1 } & 14 & 21 & 17 & 14 & 17 & 19 & 20 & 16 \\\hline \text { Course 2 } & 20 & 18 & 22 & 15 & 23 & 21 & 19 & 15 \\\hline\end{array}$$ Assume that the scores are normally distributed. Does the data provide sufficient evidence at the 5% level of significance to infer that the marks from course 1 are lower than those from course 2?
