A random sample of testimonials for texting and driving videos and number of car crashes was measured, and the computer output for regression was obtained:

R-sq. = 70.96% R-sq.(adj) = 63.70%

Part A: Use the computer output to determine the LSRL. Identify all the variables used in the equation. (3 points)

Part B: What proportion of the variation in car crashes is explained by its linear relationship to video testimonials? Explain. (4 points)

Part C: Determine if decreased accidents were caused by texting and driving videos. Explain your reasoning. (3 points)
