Can the cost of flying a commercial airliner be predicted using regression analysis? If so, what variables are related to this cost? A few of many variables that can potentially contribute are type of plane, distance, number of passengers, amount of luggage/freight, weather condition, direction of destination, or even pilot skill. Suppose a study is conducted using only Boeing 737s traveling 800 km on comparable routes during the same season of the year. Can the number of passengers predict the cost of flying such routes? It seems logical that more passengers result in more mass and more baggage, which could, in turn, result in increased fuel consumption and other costs. Suppose the data displayed below are the cost and associated number of passengers for thirty-six 800-km commercial airline flights using Boeing 737s during the same season of the year. We will use these data to develop a regression model to predict cost by number of passengers. The data in the CostofFlights.csv contains the data on the cost and number of passengers of 36 observations (a) Use R studio to estimate this model. Use four-decimals in each of your teast-squares estimatesyour answer. Cost- + 1 Number of Passengers (b) Find the coefficient of determination. Expresses as a percentage, and use two decimal places in your answer. % (c) in the context of the data, interpret the meaning of the coefficient of determination A. The percentage found above is the percentage of variation in the cost of flying a 800-km commercial flight using Boeing 737s that can be explained by its linear dependency with the number of passengers. OB. There is a weak, positive linear relationship between the cost of flying a 800-km commercial flight using Boeing 737s and the number of passengers. OC. There is a strong, positive linear relationship between the cost of flying a 800-km commercial flight using Boeing 737s and the number of OD. The percentage found above is the percentage of variation in the number of passengers that can be explained by its linear dependency with tho cost of flying a 800 km commercial flight using Boeing 737s. passengers (d) Find the standard deviation of the prediction/regression, using three decimals in your answer EE
