The adult screwworm fly is metallic blue and three times the size of the housefly. The screwworm lays its eggs in the wounds of warm-blooded animals and causes a serious infection. An experiment was carried out with the aim of controlling this population. Screwworm pupae were exposed to a radiation dose of 2500 rad in the hope of sterilizing most of the males. Since females mate only once, mating with a sterile male will produce sterile eggs. It was found that after irradiation, 415 of the 500 observed matings resulted in sterile eggs. a. What is the margin of error for the 95% confidence ratio of sterile matings produced by this dose? = Answer b. What is the upper value of the 95% confidence interval for the population proportion? = Answer c. What is the lower value of the 95% confidence interval for the population proportion? = Answer
