Regression Analysis and Credit Balance

AJ DAVIS impart a scatterplot for credence residue vs. coat of it, including the graph of the best scene line. stage. acquire the equality of the best satisfy line, which describes the relationship amid CREDIT residual and SIZE 2591+ 403. 221 Determine the coefficient of correlation. see. .75/ r-sq(56. 6%). in that location is a delicate correlation. Determine the coefficient of determination. Interpret. 56. 6% Test the expediency of this fixing copy (use a both tail examination with ? =. 05). Interpret your results, including the p- encourage. P-value=0. pass the null hpothesis.T value 7. 9147 Based on your findings in 1-5, what is your prospect about apply SIZE to annunciate CREDIT BALANCE? Size is a good holloor for course credit equilibrize. regard the 95% potency interval for beta-1 (the commonwealth slope). Interpret this interval. (300. 79, 505. 66) employ an interval, estimate the norm credit residuum for clients that have home size of 5. In terpret this interval. (4368. 20, 4846. 90) employ an interval, bid the credit balance for a customer that has a dwelling size of 5. Interpret this interval. (3337. 87, 5877. 23)What can we phrase about the credit balance for a customer that has a household size of 10? Denotes a point that is an extreme outlier in the predictors. Using MINITAB run the eight-fold regression psychoanalysis using the variables INCOME, SIZE and YEARS to predict CREDIT BALANCE. evoke the equation for this duple regression gravel. belief balance= 1276. 02+ 32. 2719 income(1000) + 346. 852 size + 7. 88209 days. Is this multiple regression model give away than the linear model that we generated in split 1-10? Yes. Reject geezerhood there is no corralation of coefficient. Income is useful and years in faction with size and income.
