A certain flight arrives on time 83 percent of the time. Suppose 154 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 131 flights are on time. (b) at least 131 flights are on time. (c) fewer than 137 flights are on time. (d) between 137 and 141, inclusive are on time.
I know that I supposed to get the mean and standard deviation from n which is 154 and p which is .83. The issue is that I have is trying to use the statcrunch or excel, I'm not getting the right answers like for EXAMPLE: P(85)=P(Z 1.38)-P(Z<1.13) turns out to be 0.9162-0.8708 which I am not understanding how it came to that using the statcrunch. If you can show me how by taking the picture of how you're putting it in the statcrunch, please do.
