The table displays the frequency of scores for a calculus class on an exam. The mean of the exam scores is 3.5. Score 1 2 3 4 5 Frequency 1 3 f 13 4 a. What is the value of f in the table? b. What is the mode of all the exam scores? c. What is the median of all the exam scores?

f=11

Mode=4

Median=4

Explanation:

We are given that

a.Mean of the exam score,=3.5

Score(x)   frequency   C.F

1                  1                 1

2                  3                4

3                  f                 15(4+f=4+11)

4                  13               28

5                   4               32

Using the formula

b.Mode:The number which is repeat most times .

4 repeat most times

Hence, mode of all exam scores=4

N=32

N is even

Median=

answer: 230 miles ( vote ! )
