[Concert Nation] Concert Nation, INC. is a nationwide promoter of rock concerts. The president of the company wants to develop a model to estimate the revenue of a major concert event at large venues {such as Ford Field, Madison Square Gardens) for planning marketing strategies. The company has collected revenue data of 34 recent large concert events. For each concert, they have also recorded the attendance, the number of concession stands in the venue, and the Billboard chart of the artist in the week of each event. This data is available in \"Part B - Data Set for Assessment Assig-mnentxslx\". They have two potential models that could explain the revenue. The two competing models are: Model A: Revenue = 55! + 31\"}! ttendance + 32A Concession + ngBttlb-aard + EA Model B: Revenue = g + fAttendanca + Bftttboard + EB Run regression on both models. Use only the regression outputs of the two models and the original data to answer questions 14 to 20 below. 4. [2 pt] Let's consider the model A first. What does the result of Ftest indicate? (a) The p-value of F -test is 107.63. Thus, the model does not signicantly explain the revenue. (b) The p-value of F -test is close to zero. Thus, all independent variables in the regression model are statistically signicant. (c) The p-value of Ftest is close to zero. This indicates that at least some independent variables in the regression model significantly explain the revenue. (d) This indicates weak evidence of a linear relationship, because the p-value is very low
