The mean arrival rate of flights at OâHare Airport in marginal weather is 195flights per hour with a historical standard deviation of 13 flights. To increase arrivals, a new air traffic control procedure is implemented. In the next 30 days of marginal weather, the mean arrival rate is 200 flights per hour. a. Set up a right-tailed decision rule at Î± = 0.025 to decide whether there has been a significant increase in the mean number of arrivals per hour.
b. Carry out the lest and make the decision. Is it close? Would the decision be different if you used Î±=.01?
c. What assumptions are you making, if any?
