2. 1. The Safety Director of Honda USA took samples at random from the file of minor accidents and classified them according to the time the accident took place. The sample data is as follows:

8am to 9am 6 accidents
9am to 10 am 6 accidents
10am to 11 am 20 accidents
11am to noon 8 accidents
Noon to 1pm 7 accidents
1pm to 2pm 8 accidents
2pm to 3pm 10 accidents
3pm to 4pm 6 accidents

At the 0.01 level of significance, are the accidents evenly distributed throughout the day?

2. For many years TV executives used the guideline that 30 percent of the audience were watching each of the prime-time networks and 10 percent were watching cable stations on a weekday night. A random sample of 500 viewers in the Tampa-St. Petersburg area last Monday night showed that 165 homes were tuned in to the ABC affiliate, 140 to the CBS affiliate, 125 to the NBC affiliate, and the remainder were viewing a cable station. At the 0.05 level of significance, can we conclude that the old guideline is still reasonable?

Hello (again! Anywho... I was just wondering what would be the value of 2bc if b=20 and c=12. My theory is either 64 or 480? b/c 2 times b (20) equals 40 and 2 times c (12) equals 24 and 24+40 equals 64.
