Question

A highway department executive claims that the number of fatal accidents which occur in her state does not vary from month to month. The results of a study of 161161 fatal accidents were recorded. Is there enough evidence to reject the highway department executive's claim about the distribution of fatal accidents between each month?

Month	Jan	Feb	Mar	Apr	May	Jun	Jul	Aug	Sep	Oct	Nov	Dec
Fatal Accidents	16	11	19	11	10	13	13	10	13	16	18	11

Step 1 of 10: State the null and alternative hypothesis.

Step 2 of 10: What does the null hypothesis indicate about the proportions of fatal accidents during each month?

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 fatal accidents that occurred in January. Round your answer to two decimal places.

Step 5 of 10: Find the expected value for the number of fatal accidents that occurred in October. 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 0.0050.005 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 0.0050.005 level of significance.

Step 10 of 10: State the conclusion of the hypothesis test at the 0.0050.005 level of significance.
