Refer to the Data Display printout to answer this question. Which of these is the equation of the regression line? 1Q Score = .4925 - 22.26(Mus.Apt.) Mus.Apt. = .4925 - 22.26(IQ Score) Mus.Apt. = -22.26 + .4925(1Q Score) O IQ Score = -22.26 + .4925(Mus.Apt.) 1Q Score = Constant + .4925xRefer to the Data Display printeut to answer this question. From the printout. we can determine the test statistic {t} we'd use to test the hypothesis HO: Bi = 0. Its value is: (Dates. ().oooa43.
