The National Highway Traffic Safety Administration reported the percentage of traffic accidents occurring each day of the week (Time, March 12, 2012). Assume that a sample of 420 accidents provided the following data.
| Sunday |

Tuesday |
Wednesday |
Thursday |
Friday |
Saturday |
| 66 |
50 |
53 |
47 |
55 |
69 |
80 |
Conduct a hypothesis test to determine if the proportion of traffic accidents is the same for each day of the week. What is the p-value? Using a .05 level of significance, what is your conclusion?
