1. Identify the steps in interpreting a regression model. Interpret the following data:

Y = 5.0 + .30X1 where the dependent variable equals turnover intentions for line managers and the independent variable equals the number of employees supervised

Y = 250 - 4.0X1 where the dependent variable is the number of hits on a new banner ad and the independent variable is the number of weeks the ad has run

2. Calculate the mean average miles per gallon. Compute the sample variance and sample standard deviation. Determine the most appropriate statistical test using the 0.5 significance level. Provide your findings in the space provided.

3. Comment on the appropriateness of the statistical test used (make sure that your response includes information on the types of variables used and the scales of measurement). Describe an alternative approach that may be used.
