I have worked on this problem and continue to conclude that the answer is yes, but cannot find the correct p-value. Can someone explain how to calculate the P value of this question properly?


The mean arrival rate of ights at O'Hare Airport in marginal weather is 195 ights per hour. To increase arrivals, a new air trafc control procedure is implemented. Data was collected for the next 30 days of marginal weather. The data for the arrival rate per hour is given in worksheet O'Hare of the Excel Workbook for the exam. Is there enough evidence, at 0( = .05 to conclude that the mean arrival rate in marginal weather under the new procedure is greater than 195? CA. Yes, because the p-value of the upper tailed testis .9715O(=.05. A C. No, because the p-value of the of the upper tailed test is .4857> O(=.05. A D.Yes, because the p-value of the upper tailed test is .0285
