Two different tests are designed to measure employee productivity and dexterity.Several employees are randomly selected and tested with these results. Productivity Dexterity 234925532859214221472553265530633467367529523155\begin{array} { c | c } \text { Productivity } & \text { Dexterity } \\\hline 23 & 49 \\\hline 25 & 53 \\28 & 59 \\21 & 42 \\21 & 47 \\25 & 53 \\26 & 55 \\30 & 63 \\34 & 67 \\36 & 75 \\29 & 52 \\31 & 55\end{array} Productivity 232528212125263034362931 Dexterity 495359424753556367755255 Using a 5% level of significance,perform a nonparametric test to determine if there is a monotonic association between an employee's productivity and their dexterity.Assume that rank ties will have little influence on your result.

H0: There is no monotonic association between an employee's productivity and their dexterity. HA: There is a monotonic association between an employee's productivity and their dexterity. rs = 0.888,Test statistic: t = 13.28,P-value = 0.000000056 Reject the null hypothesis.There is sufficient evidence to suggest a monotonic association between an employee's productivity and their dexterity.
