question 138

Essay

A random sample of 10 employees of an engineering company was selected. Each employee was asked to
report the number of sick days he/she claimed on Wednesdays and Fridays of the previous calendar year. Use
this information to test the employer's claim that more employees call in sick on Fridays than on Wednesdays.
Use $\alpha = 0.05$ 5. Assume that the differences between Wednesday's and Friday's sick day counts is normally
distributed. $$\begin{array} { | c | c | } \hline \text { Wednesdays } & \text { Fridays } \\\hline 1 & 2 \\\hline 1 & 3 \\\hline 0 & 1 \\\hline 2 & 1 \\\hline 1 & 6 \\\hline 3 & 2 \\\hline 0 & 4 \\\hline 1 & 0 \\\hline 4 & 5 \\\hline 2 & 2 \\\hline\end{array}$$ Include your null and alternative hypotheses, the test statistic, P-value or critical value(s), conclusion about the null
hypothesis, and conclusion about the claim in your answer.
