Request Description
Using MINITAB perform the regression and correlation analysis for the data on CREDIT BALANCE (Y) and SIZE (X) by answering the following. Generate a scatterplot for CREDIT BALANCE vs. SIZE, including the graph of the "best fit" line. Interpret. Determine the equation of the "best fit" line, which describes the relationship between CREDIT BALANCE and SIZE. Determine the coefficient of correlation. Interpret. Determine the coefficient of determination. Interpret. Test the utility of this regression model (use a two tail test with ? =.05). Interpret your results, including the p-value. Based on your findings in 1-5, what is your opinion about using SIZE to predict CREDIT BALANCE? Explain. Compute the 95% confidence interval for beta-1 (the population slope). Interpret this interval. Using an interval, estimate the average credit balance for customers that have household size of 5. Interpret this interval. Using an interval, predict the credit balance for a customer that has a household size of 5. Interpret this interval. What can we say about the credit balance for a customer that has a household size of 10? Explain your answer.
