A researcher claims that the number of homicide crimes by season is uniformly distributed. To test this claim, you randomly select 1,204 homicides from a recent year and record the season when each happened. The table shows the results. At a = 0.10, test the researcher's claim. Spring Summer Fall Winter C... Ho: The distribution of the number of homicide crimes by season Ha: The distribution of the number of homicide crimes by season Which hypothesis is the claim? O Ho O Ha Calculate the test statistic. x² = (Round to three decimal places as needed.) Determine the P-value. P-value= (Round to three decimal places as needed.) Decide whether reject or fail to reject the null hypothesis and i the decision the context of the original claim. Ho. There enough evidence at the 10% level of significance to reject the claim that the distribution of the number of homicide crimes by season Season Frequency, f 307 317 297 283
