Click the icon to view the table that contains the number of flights that did not meet New England Air's definition of on time. a) The overall fraction of late flights is (enter your response as a real number rounded to two decimal places.) Using a 95% confidence level, the upper and lower control limits are: Upper control limit (ULp)= (enter your response as a fraction between 0 and 1 , rounded to four decimal places). Lower control limit (LL)= (enter your response as a fraction between 0 and 1 , rounded to four decimal places). b) Assume that the airline industry's upper and lower control limits for flights that are not on time are 0.1000 and 0.0500, respectively. Choose the correct control chart below. c) Choose the chart below that correctly plots the percentage of late flights in each sample. Do all samples fall within New England Air's control limits? No Yes When one falls outside the control limits, what should be done? A. Nothing should be done. B. An investigation, leading to corrective action, should be done. C.
