  1. Define the association between variables selected?
  2. What is the probability a car on the list will be less $29,000 and what is the probability the car will be more than $29,000?
  3. Develop a 95% confidence interval estimate that the higher the price of the car, the higher the road test scores. (For assistance, see the Excel steps on page 415 of your textbook).
      1. What are the upper and lower limits for car cost and road test score?
  4. Perform a regression analysis for predicated reliability and price to develop an estimated regression equation that could be used to predict the reliability and price.
