6. Fill in the missing values in the following table of relative frequency, labelled A- J. Show how you calculate each value, and put your final answer for each value in the table below (e.g., replace "A" with your found value). The method you use can be different from mine, but you must show how you arrive at each value. Hint: go in order. Find A, then B, etc. Tutorial video 3 should be very helpful here.
