To determine whether extra personnel are needed for the day, the owners of a water adventure park would like to find a model that would allow them to predict the day's attendance each morning before opening based on the day of the week and weather conditions. The model is of the form
a. Interpret the estimated model coefficients.
b. Is there sufficient evidence to conclude that this model is useful tor the prediction of daily attendance? Use a = .05.
c. Is there sufficient evidence to conclude that the mean attendance increases on weekends? Use CY = .10.
d. Use the model to predict the attendance on a sunny weekday with a predicted high temperature of 95°F.
e. Suppose the 90% prediction interval for part d is (645,1,245). Interpret this interval
