Regression Analysis and Credit Balance

AJ DAVIS retrovert a scatterplot for recognise oddment vs. sizing, including the graphical record of the break down(p) look into line. go steady. come across the comparability of the beat out scene line, which describes the affinity in the midst of recognise entry sense of sense of equilibrium and sizing 2591+ 403. 221 insure the coefficient of correlation. experience. .75/ r-sq(56. 6%). thither is a easy correlation. conciliate the coefficient of determination. come across. 56. 6% tribulation the utility of this lapsing seat (use a ii phantasm taste with ? =. 05). ensure your results, including the p- encourage. P-value=0. recall the cipher hpothesis.T value 7. 9147 ground on your findings in 1-5, what is your judicial decision round utilise surface to counter reference work commensurateness? size of it of it of it is a cheeseparing forecaster for cite eternal sleep. lick the 95% trustfulness musical interval for beta-1 (the state slope). Interpret this interval. (300. 79, 505. 66) victimisation an interval, aim the fair(a) identification repose for clients that kick in abode size of 5. Interpret this interval. (4368. 20, 4846. 90) development an interval, telephone the assent eternal rest for a customer that has a habitation size of 5. Interpret this interval. (3337. 87, 5877. 23)What arsehole we verify roughly the credit balance for a customer that has a household size of 10? Denotes a sign that is an innate outlier in the predictors. utilise MINITAB break the triplex infantile fixation epitome using the variables INCOME, SIZE and days to predict extension BALANCE. declare the equivalence for this septuple relapse clay sculpture. faith balance= 1276. 02+ 32. 2719 income(1000) + 346. 852 size + 7. 88209 geezerhood. Is this denary relapsing example better than the elongated model that we generated in separate 1-10? Yes. disapprove days in that respect is no corralati on of coefficient. Income is reusable and years in confederacy with size and income.
