If below is the table,

1.If you want to complete the relative frequency table to answer the question - 'Among left-handed writers, what proportion have neat handwriting. To do this we calculate the row-relative frequency.

Find the row totals

Now calculate the row-relative frequencies:

So among left-handed users, \frac{6}{14} or 0.43 had neat writing.

2.If you want to determine the percentage of right-handed writers who the teacher determined have messy handwriting, convert 0.47 into percentage by multiplying with 100 to get 47%. This is shown below:

I UNDERSTOOD WHAT YOU WANTED TO ASK
