See the attached grade point averages. One hundred seniors were chosen at random from a graduating class at a university and their grade-point averages recorded.

A) construct a frequency and relative frequency table using a class interval of 0.2 starting at 1.95

B) Construct a frequency polygon and a cumulative frequency polygon

C) What is the probability of a GPA drawn at random from the sample being over 2.95?

D) Construct a cumulative frequency and relative cumulative frequency table.

Please explain steps so I can learn. Thank you
