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:

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.
