According to the US Dept of Transportation, 70% of car accidents occur within 25 miles of a driver's home, 20% occur in distances between 25 and 50 miles, and 10% of car accidents occur in distances greater than 50 miles from their home. We examine traffic data in NYC and compare the location of the accidents to driver's home zip codes to count the number of accidents seen in each range. |Distance From Home | Less Than 25mi Between 25 and 50 mi | Greater than 50mi # of Accidents 155 41 12 Using a 10% level of significance, does our observed data match the distribution given by the Department of Transportation?

According to the US Dept of Transportation, 70% of car accidents occur within 25
miles of a driver's home, 20% occur in distances between 25 and 50 miles, and 10%
of car accidents occur in distances greater than 50 miles from their home.
We examine traffic data in NYC and compare the location of the accidents to driver's
home zip codes to count the number of accidents seen in each range.
