Use the following to answer questions 7-8; A simple random sample of 100 flights of a large airline (call this airline 1) showed that 64 were on time. A simple random sample of 100 flights of another large airline (call this airline 2) showed that 80 were on time. Let p, and p, be the proportion of all flights that are on time for these two airlines. 7. If the 90% confidence interval for the difference p, - p, is-0.157 =0.102. Is there 2 evidence of a difference in the on-time rate for the two airlines? To determine this, test the hypotheses Hip, =p, versus Hip, Op,. Based on the 90% confidence interval, answer each of the following questions with yes, no, or can't tell. Is the P-value less than 0.001? Is it true that 0.05
