4 1 point 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: Regression Equation: dom 22.69+0.876 nondom Prediction intervals for x-10: Prediction Fit SE Fit 95% CI 95% Pl 31.4532 0.793027 (29.8674, 33.0389) (21.2288, 41.6775) Using the information above, what is the best choice for the explanation of what the 95% P.I. for x=10 means, in this case: O I am 95% sure that any student can write between 21.23 and 41.68 letters in 15 seconds with their dominant hand. I am 95% sure that the number of letters that one student can write in 15 seconds with their dominant hand, if they did write 10 letters with their non-dominant hand, is between 21.23 and 41.68. There is a 95% chance that students can write between 21.23 and 41.68 letters in 15 seconds with their dominant hand. I am 95% sure that the mean number of letters that students can write in 15 seconds with their dominant hand if they can write 10 letters with their non-dominant hand is between 21.23 and 41.68.
