The 2002 general Social Survey asked a large number of people how much time they spent watching TV
each day. The mean number of hours was 4.16 with a standard deviation of 2.23. Assume that in a sample

TV watching times is normally distributed. Under 10% significance level can you conclude that the
population standard deviation of TV watching times for teenagers is different from 2.23?
