Question
A researcher analyzes the factors that may influence amusement park attendance. She estimates the following model: Attendance = 0 + 1Price + 2Temperature + 3Rides + , where Attendance is the daily attendance (in 1,000s), Price is the gate price (in $), Temperature is the average daily temperature (in °F), and Rides is the number of rides at the amusement park. A portion of the regression results is shown in the accompanying table.
When testing whether Price is significant in explaining Attendance, the value of the test statistic is ________.

Correct Answer: Option (C) -4.0850
since
Test statistic = -1.201/0.294 = -4.0850
Here P-value of Price is <0.05,so we reject H0
thus we conclude that the population regression coefficient of price is not equal to zero
i.e. Price is significant in explaining Attendance
