Suppose that 10% of the fields in a given agricultural area with about 2,500 fields are infested with the sweet potato white fly. one hundred fields in this area are randomly selected and checked for white fly.
a. using the exact binomial calculation, find the probability that from 4 to 16 randomly selected fields are infected.
b. using the normal approximation, find the probability that from 4 and 16 randomly selected fields are infected. find the probability in two ways: with and without the continuity correction. how do the answers from the two methods compare, and how do you account for the difference?
c. sketch the probability distribution and the area you found when using the normal approximation with the continuity correction.

1. there are 25 students who started computer programming in elementary school and 25 students who started computer programming in middle school. the first group had a mean final project grade of 95% and the second group had a mean final project grade of 92%. the line plot shows the differences after 10 rerandomizations. determine whether the difference in the means of the two groups is significant based on the line plot. explain your answer.
