The statistical and regression questions are listed below:
- What is the value of the simple correlation between TICKETS and COST?
- If you are able to determine the answer, is showing the film in more theatres associated with higher ticket sales (with cost and holiday opening held constant) with α = 0.05? (Justify your response).
- If you are able to determine the answer, do higher cost movies have higher ticket sales (with THEATRE, HOLIDAY and movie genre held constant) with α = 0.05? (Justify your response).
- If you are able to determine the answer, do movies opening on holiday weekends have different ticket sales than those opening on non-holiday weekends (with COST held constant) with α = 0.05? (Justify your response).
- Interpret the coefficient for COST in Model 1 (that is, interpret the estimated value of 0.0944 without considering whether or not this value is "statistically significant").
