Randomly selected deaths of motorcycle riders in a region of the northern hemisphere are summarized in the accompanying table. Use a 0.05 significance level to test the claim that such fatalities occur with equal frequency in the different months. How might the result we explained? Month Humber Month Jan. Feb. March April 11 7 12 July Aug. Sept Number 26 27 23 Determine the null and alternative hypotheses. Ho: #₂: May 16 20 Oct. Nov. 8 15 Calculate the test statistic, Calculate the P-value. June 30 Dec. 8 (Round to three decimal places as needed.) value=(Round to three decimal places as needed.) What is the conclusion for this hypothesis test? Because the P-value is low might the results be explained? OA. People are equally likely to drive motorcycles at any time of the year. OB. People are less likely to drive motorcycles during the summer, and more likely during the winter. OC. People are more likely to drive motorcycles during the summer, and less likely during the winter. OD. People are more likely to drive motorcycles during the spring, and less likely during fall. the significance level, Ho. There sufficient evidence to warrant rejection of the claim that motorcycle fatalities occur with equal frequency in the different months.

Use a 0.05 significance level to test the claim that such fatalities occur with equal frequency in the different months. How might the results be explained? Jan. Feb. March April May 7 16 20 July Aug. Sept. Oct. Nov. 11 12 23 15 8 Month Number Month Number 26 27 Determine the null and alternative hypotheses. Ho H₂: Calculate the test statistic, x²=(Round to three decimal places as needed.) Calculate the P-value. P-value = What is the conclusion for this hypothesis test? June 30 Dec. 8 (Round to three decimal places as needed.) Because the P-value is How might the results be explained? the significance level, Ho.
