Essay

Perform the indicated goodness-of-fit test. Be sure to state the hypotheses and the significance level, to obtain the criticalvalue, to compute the value of the test statistic, and to state your conclusion.
-In 1990, workplace accidents were distributed on workdays as follows. $$\begin{array}{l} \begin{array} { l | c c c c c } \text { Day } & \text { Mon } & \text { Tues } & \text { Wed } & \text { Thur } & \text { Fri } \\ \hline \text { Percentage } & 25 & 15 & 15 & 15 & 30 \end{array}\\\\ \text { In 1995, a random sample of } 100 \text { workplace accidents yielded the following data. }\\\\ \begin{array} { l | c c c c c } \text { Day } & \text { Mon } & \text { Tues } & \text { Wed } & \text { Thur } & \text { Fri } \\ \hline \text { Percentage } & 21 & 13 & 15 & 16 & 35 \end{array} \end{array}$$ Do the data provide sufficient evidence to conclude that the distribution of workplace accidents in 1995 differs from the 1990 distribution? Perform the hypothesis test at the 0.01 level of significance.
