question 86

Multiple Choice

A researcher analyzes the factors that may influence amusement park attendance. She estimates the following model: Attendance = β₀ + β₁Price + β₂Temperature + β₃Rides + ε, 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 Rides is significant at the 1% significance level, she ________.

• A) rejects H₀: β₃ = 0, and concludes that Rides is significant
• B) does not reject H₀: β₃ = 0, and concludes that Rides is significant
• C) rejects H₀: β₃ = 0, and cannot conclude that Rides is significant
• D) does not reject H₀: β₃ = 0, and cannot conclude that Rides is significant
