question 44

Short Answer

Employee
Four employees are monitored to determine whether there is any difference in the proportions of acceptable parts produced by the employees.The sample of parts produced is given below. $$\begin{array}{l}\text { Employee }\\\begin{array} { | l | c c c c | c | } \hline \text { Quality } & \mathbf { 1 } & \mathbf { 2 } & \mathbf { 3 } & \mathbf { 4 } & \text { Total } \\\hline \text { Acceptable } & 265 & 270 & 225 & 180 & 950 \\\text { Unacceptable } & 10 & 5 & 15 & 20 & 50 \\\hline \text { Total } & 275 & 275 & 250 & 200 & 1000 \\\hline\end{array}\end{array}$$
-These data provide the information for testing the hypothesis that the proportion of unacceptable is the same for the four employees.Calculate the test statistic.
