Question
A dataset shows the number of capital letters that a student can write in 15 seconds using the non- dominant hand (X) versus the same thing for the dominant hand (Y). The data is for 63 students. Here is computer output: Model Summary R-sq R-sq(adj) R-sq(pred) 5.05128 33.95% 32.35% 30.45% Coefficients Term Coef SE Coef T-Value P-Value VIF Constant 21.44 2.38 10.92 0.000 nondom 1.22 0.351 5.82 0.000 1.00 Regression Equation dom = 21.44 + 1.22 nondom Using the equation of the line of best fit, predict the number of dominant hand letters a person can write in 15 seconds if they can write 30 letters with the non-dominant hand. This is a point estimate not a confidence interval.
