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 information above, what is the best choice for the explanation of what the 95% P.I. for x=10 means, in this case:

Group of answer choices

A) There is a 95% chance that students can write between 21.23 and 41.68 letters in 15 seconds with their dominant hand.

B) 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.

C) 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.
