The director of special events for Sun City believed that the amount of money spent on fireworks displays for the Fourth of July was predictive of attendance at the Fall Festival held in October. She gathered the following data to test her suspicion. 4th of July ($000) Fall Festival (000) 4th of July ($000) Fall Festival (000) 10.6 5.7 9.0 9.5 8.5 6.4 10.0 13.1 12.5 12.4 7.5 6.6 9.0 10.2 10.0 10.1 5.5 6.0 6.0 6.1 12.0 11.1 12.0 7.5 8.0 7.5 10.5 10.9 7.5 8.4 a-1. Compute and report the regression equation that predicts “fall festival attendance” with “amount spent on Fourth of July fireworks”. (Round your answers to 2 decimal places.) Fall = ________+________ (July $ on Fireworks) a-2. Report the coefficient of determination. (Round your answer to 2 decimal places.) R2_________% a-3. Interpret the regression coefficient.
