Each observation in a random sample of 99 bicycle accidents resulting in death was classified according to the day of the week on which the accident occurred. Data consistent with information are given in the following table.
Day of Week Frequency
Sunday
13
Monday
12

Based on these data, is it reasonable to conclude that the proportion of accidents is not the same for all days of the week? Use a = 0.05.
Calculate the test statistic. (Round your answer to two decimal places.)
x²=
Use technology to calculate the P-value. (Round your answer to four decimal places.)
P-value=
State the conclusion in the problem context.
O Fail to reject Ho. We have convincing evidence that the proportion of accidents is not the same for all days of the week.
O Reject Ho. We do not have convincing evidence that the proportion of accidents is not the same for all days of the week.
O Fall to reject Ho. We do not have convincing evidence that the proportion of accidents is not the same for all days of the week.
O Reject Ho. We have convincing evidence that the proportion of accidents is not the same for all days of the week.
