Question: A one-sided confidence interval for p can be written as p < + E or p > - E, where the margin of error E

A one-sided confidence interval for p can be written as p < + E or p > - E, where the margin of error E is modified by replacing zα/2 with zα. If Air Borealis wants to report an on-time performance of at least x percent with 95% confidence, construct the appropriate one-sided confidence interval and then find the percent in question. Assume that, from a random sample of 750 flights, 630 are on time.
