Question
Use the accompanying regression table to answer the following questions. Complete parts (a) through (c). a) How was the t-ratio of 154.0 computed for Paid Attendance? (Show what is computed using numbers from the table.) A. 0.0005/0.0047 B. -18.031/-0.117 C. 154.988/0.009067 D. 464.964/0.670947 E. 0.005/0.077 F. 0.077/0.0005 b) How many weeks are induced in this regression? How can you tell? A. 77 weeks arc included, because the degrees of freedom is 74, and that's equal to (number of cases) - (number of predictor variables). B. 75 weeks arc included, because the degrees of freedom is 74, and that's equal to (number of cases) -1. C. 78 weeks arc included, since the degrees of freedom is 74, and that's equal to (number of cases) - (number of predictor variables) -1. D. 74 weeks arc included, because the degrees of freedom is 74. c) The t-ratio for the intercept is negative. What does that mean? A. The t-ratio is negative because as number of shows increases, the average ticket price goes down. B. The t-ratio is negative because as the attendance goes down, the average ticket price increases. C. The t-ratio is negative because the coefficient is negative. D. The t-ratio is negative because as the attendance goes down, the average ticket price increases. Data were gathered from ticket sales of musical shows in a particular city for meat weeks of a recent time period. (A few weeks are missing data.) The variables are Receipts (exist million), Paid Attendance (thousands). # Shows, and Average Ticket Price (exist). Dependent variable is:Receipts (SM) R squared = 99.9% R squared (adjusted) = 99.9% s = 0.0952 with 74 degrees of freedomExplanation / Answer
Answer to the questions here:
a. F) is right
t ratio is calculated as Xbar-Mean / SE = (.077-0)/.0005
F is the right option
b. Since there are 77 df the n = df+1 = 78. These many weeks.
c. If the t ratio is negative as the coefficient is negative. SE is always postivie. Since t = Coeff-0/SE, and Coeff is <0, and SE>0, we have t is -ive.
