Each observation in a random sample of 102 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. 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 α = 0.05. (Round your answer to two decimal places.)
Day of Week | Frequency |
Sunday | 15 |
Monday | 12 |
Tuesday | 12 |
Wednesday | 16 |
Thursday | 15 |
Friday | 18 |
Saturday | 14 |
