A telephone company claims that the service calls which they receive are equally distributed among the five working days of the week. A survey of 110 randomly selected service calls was conducted. Is there enough evidence to refute the telephone company's claim that the number of service calls does not change from day-to-day? Days of the Week Mon Tue Wed Thu Fri Number of Calls 24 26 17 20 23 Copy Data Step 2 of 10: What does the null hypothesis indicate about the proportions of service calls received each day? Step 3 of 10: State the null and alternative hypothesis in terms of the expected proportions for each category. Step 4 of 10: Find the expected value for the number of service calls received on Monday. Round your answer to two decimal places. Step 5 of 10: Find the expected value for the number of service calls received on Tuesday. Round your answer to two decimal places. Step 6 of 10: Find the value of the test statistic. Round your answer to three decimal places. Step 7 of 10: Find the degrees of freedom associated with the test statistic for this problem. Step 8 of 10: Find the critical value of the test at the 0.010.01 level of significance. Round your answer to three decimal places. Step 9 of 10: Make the decision to reject or fail to reject the null hypothesis at the .01 level of significance. Step 10 of 10: State the conclusion of the hypothesis test at the 0.010.01 level of significance.
