Suppose flight AA380 (from NYC to Chicago) arrives on time 87% of the time. Suppose 120...
A certain flight arrives on time 87 percent of the time. Suppose 144 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 124 flights are on time. (b) at least 124 flights are on time. (c) fewer than 126 flights are on time. Id between 126 and 127 Inclusive are on time
A certain flight arrives on time 90 percent of the time. Suppose 185 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 170 flights are on time. (b) at least 170 flights are on time. (c) fewer than 174 flights are on time. (d) between 174 and 178, inclusive are on time.
A certain flight arrives on time 80 percent of the time. Suppose 174 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 148 flights are on time. (b) at least 148 flights are on time. (c) fewer than 133 flights are on time. (d) between 133 and 150, inclusive are on time.
A certain flight arrives on time 86 percent of the time. Suppose 160 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 150 flights are on time. (b) at least 150 flights are on time. (c) fewer than 133 flights are on time. (d) between 133 and 136, inclusive are on time.
A certain flight arrives on time 89 percent of the time. Suppose 187 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 169 flights are on time. (b) at least 169 flights are on time. (c) fewer than 176 flights are on time. (d) between 176 and 179 inclusive are on time.
A certain flight arrives on time 88 percent of the time. Suppose 158 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 144 flights are on time. (b) at least 144 flights are on time. (c) fewer than 147 flights are on time. (d) between 147 and 148 inclusive are on time.
A certain flight arrives on time 81 percent of the time. Suppose 135 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 123 flights are on time. (b) at least 123 flights are on time. (c) fewer than 117 flights are on time. (d) between 117 and 123 inclusive are on time. (Round to four decimal places as needed.)
part c, please A certain flight arrives on time 90 percent of the time. Suppose 122 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 112 fights are on time (b) at least 112 fights are on time. (c) fewer than 113 fights are on time. (d) between 113 and 117, Inclusive are on time (a) P(112) - 0.0064 (Round to four decimal places as needed.) (b) PIX2 112) - 0.304...

Use the normal approximation to the binomial to approximate the probability that (a) exactly 105 flights are on time. (b) at least 105 flights are on time. (c) fewer than 103 flights are on time. (d) between 103 and 111, inclusive are on time.
A certain flight arrives on time 86 percent of the time. Suppose 162 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 152 flights are on time. (b) at least 152 flights are on time. c) fewer than 144 flights are on time. (d) between 144 and 147, inclusive are on time. a) P(152)= (Round to four decimal places as needed.)
