The following data set gives the difference between the winning and?

losing scores in 50 randomly observed high school basketball games: 2, 12, 1, 2, 12, 5, 14, 2, 45, 9, 1, 8, 18, 28, 9, 4, 30, 16, 4, 12, 8, 13, 20, 9, 17, 13, 49, 17, 13, 4, 14, 2, 12, 29, 8, 9, 11, 4, 6, 22, 4, 20, 23, 9, 14, 11, 8, 8, 2, 8.

A) Make a frequency table detailing the occurrence of each score difference.

B) Find the relative frequency of each score difference observed.

C) Make a stem-and-leaf plot of the data from this experiment.

D) Develop appropriate intervals and make a histogram for this data

I've made the frequency table if someone can just check it and then I don't know where to go from there?

a) Frequency table:

( value, frequency)

(1,2)

(2,5)

(4,5)

(5,1)

(6,1)

(8,6)

(9,5)

(11,2)

(12,4)

(13,3)

(14,3)

(16,1)

(17,2)

(18,1)

(20,2)

(22,1)

(23,1)

(28,1)

(29,1)

(30,1)

(45,1)

(49,1)

Okay and I have done C. I need help with B and D.

C) Stem-and-leaf is just listing the numbers in sorted order, with the tens on one side of a dividing line, and the ones (last digits) on the other. You write all the individual last ones on the same line:

0 | 1 1 2 2 2 2 2 4 4 4 4 4 5 6 8 8 8 8 8 8 9 9 9 9 9

1 | 1 1 2 2 2 2 3 3 3 4 4 4 6 7 7 8

2 | 0 0 2 3 8 9

3 | 0

4 | 5 9
