Use the accompanying regression table to answer the following questions. Complete parts (a) through (c). E Click to view the data table. a) How was the t-ratio of 87.8 computed for Paid Attendance? (Show what is computed using numbers from the table.) OA. 487.653 O C. 0.079 OE. 0.0009 Data were gathered from ticket sales of musical shows in a particular weeks of a recent time period.

How can you tell? OA. 74 weeks are included, because the degrees of freedom is 74 O B. 75 weeks are included, because the degrees of freedom is 74, and that's equal to (number of cases)-1 O C. 77 weeks are included, because the degrees of freedom is 74, and that's equal to (number of cases)-(number of predictor variables). O D. 78 weeks are included, since the degrees of freedom is 74, and tha's equal to (number of cases)-(number of predictor variables)-1 Variable ntercept Paid Attendance 0.079 0.0009 87.8Explanation / Answer
Asnwer to the question:
a. t = 87.8
Paid attendance is .079/.0009
SInce the t statistic = B Coefficient/SE = .0070/.0009
C is right
b. The no. of weeks = dftotal + 1 = 74+3+1 = 78
df total = df regression + df residual
D is the right option
c. t-ratio for the intercept is negative as the coefficient is negative
D is the right
