Kyle received the following course grades for 10 (three-credit) courses during his freshman year:
4 comma 4 comma 4 comma 3 comma 3 comma 3 comma 1 comma 1 comma 1 comma 14, 4, 4, 3, 3, 3, 1, 1, 1, 1.
(a) find his grade point average by adding the grades and dividing by 10.
(b) write down the relative frequency table.
(c) find the mean of the relative frequency distribution in part (b).

(a) The average grade point is 2.5.

(b) The relative frequency table is show below.

(c) The mean of the relative frequency distribution is 0.3333.

Step-by-step explanation:

The given data set is

4, 4, 4, 3, 3, 3, 1, 1, 1, 1

(a)

The average grade point is

Therefore the average grade point is 2.5.

(b)

The relative frequency table is show below:

x                 f                  Relative frequency

4                3                

3                3                

1                 4                

(c)

Mean of the relative frequency distribution is

Therefore the mean of the relative frequency distribution is 0.3333.

step-by-step explanation:

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
