A researcher wanted to determine whether certain accidents were uniformly distributed over the days of the week. The data show the day of the week for n= 300 randomly selected accidents. Is there reason to believe that the accident occurs with equal frequency with espect to the day of the week at the a = 0.05 level of significance? E Click the icon to view the table. Let p = the proportion of accidents on day i, where i = 1 for Sunday, i= 2 for Monday, etc. What are the null and alternative hypotheses? H,: At least one proportion is different from the others. O B. Ho At least one proportion is different from the others. H, P, "P2="P, = H,: More accidents occur earlier in the week than later. O D. H,: More accidents occur later in the week than earlier. Comoute the expected counts for dav of the week.
