What are the answers for the problems below? please give me explanations as well. thank you

27. The weights for a population of monkeys from the area of Kampuchea follow a normal distribution with mean 42 pounds, and a standard deviation of 17 pounds. The weights for a population of monkeys from the Zanzibar area follow a normal distribution with a mean of 15 pounds, and a standard deviation of 3 pounds. A monkey from Kampuchea has been measured to be 44 pounds, and a Zanzibar monkey has been measured to be 19 pounds. Which of the following statements best describes the comparison between the two sample monkeys? A. The Kampuchea monkey is heavier for its breed than the Zanzibar monkey is for its breed. B. The Zanzibar monkey is heavier for its breed than the Kampuchea monkey is for its breed. C. The monkeys are about equally heavy for their respective breeds. D. There is no basis for comparison, since the monkeys come from different breeds. E. There is not enough information to compare, since the population sizes are unknown. 28. Suppose that Basketball Jones has an approximate (.85 probability of making a free throw successfully. If Basketball Jones attempts 100 free throws, what is the approximate probability that he will make at least 90 out of 100 successfully? A. .1500 B. .1038 C. .0808 D. .0618 E. .0444 29. Suppose that there is a strong linear relationship between the weight of a tiger, and the tiger's maximum running speed. A least-squares fit computed from a sample of tigers yielded the following estimated relationship between the maximum speed, in miles per hour, and weight in pounds: y=101.6 - 0.153x 150
