Question: The manager of a large supermarket chain would like to use shelf space to predict the sales of pet food. A random sample of 12 equal-sized stores is selected with the results listed above.

  1. Construct a scatter plot and then run a regression on that data if it appears that there is a direct correlation.
  2. Interpret the meaning of the slope in this problem.
  3. Predict the mean weekly sales of pet food for stores with 8 feet of shelf space for pet food. What would be the total value with a 95 % confidence level?
  4. At the .05 level of significance, is there evidence of a linear relationship between shelf space and sales?
  5. Construct a 95 % confidence interval estimate of the population slope
