A bicycle safety organization claims that fatal bicycle accidents are uniformly distributed throughout the week. The table on the right
shows the day of the week for which 778 randomly selected fatal bicycle accidents occurred. At a = 001. can you reject the claim that
the distribution is uniform? Complete parts a through d below. (a) State Ho and Ha and identify the claim. H0: The distribution of fatal bicycle accidents throughout the week is Ha: The distribution of fatal bicycle accident throughout the week is Which hypothesis is the claim? 0 ”0 0 H8 (b) Determine the critical value, Xi, and the rejection region. 2
X0 = (Round to three decimal places as needed.) Choose the correct rejection region below OA. xzsx: 03- 95%
