For purposes of this exercise, assume that these 816 bicycle accidents are a random sample of fatal bicycle accidents. Do these data support the hypothesis that fatal bicycle accidents are not equally likely to occur in each of the 3-hour time
periods used to construct the table? Test the relevant hypotheses using a significance level of a = 0.05.
Let P1. P2: P3: P4 Ps: Pe: P7, and Pg be the proportions of accidents occurring in the eight different time periods.
State the appropriate null and alternative hypotheses.
O Ho: P1 = P2 = P3 = P4 = Ps = P6 = P7 = Pg = 816
H: Ho is not true.
O Ho: P1 = P2 = P3 = P4 = P5 = P6 = P7 = Pg = 0.08

%3D
H: Ho is not true.
O Ho: P, = P2 = P3 = P4 = Ps = P6 = P7 = Pg = 0.125
H: Ho is not true.
O Ho: P, = P2 = P3 = P4 = Ps = P6 = P7 = Pg = 0.8

H: Ho is not true.
O Ho: P1 = P2 = P3 = P4 = Ps - P6 = P7 = P8 = 102
H: Ho is not true.
Find the test statistic and P-value.
