Using the attached file, please answer each number. I will post a new question with no answer required with 100 points for whoever answers this question accurately so that I get a legitimate answer and not some crazy one by someone who just wants points. Thanks!

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?

Me asap! what is the slope of this line? enter your answer in the box.
