Students in an elementary school both boys and girls were asked if they are willing to write a letter to their mother on Mother's Day as an assignment. Out of the 30 boys, only 9 answered "yes" while out of the 45 girls, 39 said that they are willing to write to their mother on Mother's Day. At 99% level of confidence, is there enough evidence to say that the proportion who said "yes" is more for girls than boys? .

The height of women ages 20-29 is normally distributed, with a mean of 64.9 inches. Assume σ=2.4 inches. Are you more likely to randomly select 1 woman with a height less than 66.8 inches or are you more likely to select a sample of 14 women with a mean height less than 66.8 inches? Explain.

Data from 14 cities were combined for a 20-year-period, and the total 280 city-years included a total of 168 homicides. After finding the mean number of homicides, find the probability that a randomly selected city has the followng number of homicides. Homicides each city-year: 0, 1, 2, 3, 4 Actual results: 155, 90, 28, 6, 1 P(0)=
