What is the mean?
round to the nearest tenth if needed.
value
frequency
1 2 3 4 5

7.2

the answer is 2.4

Mean=\frac{\sum fx}{\sum f}

Where:

f is the frequency

x is the value

\frac{3+7+5+6+2+x}{6} =5

23+x=30

x=30-23

x=7

\therefore Mean=\frac{1 \times 7 + 2 \times 1+ 3 \times 3 + 4 \times 2 + 5\times 2}{15}

                      =\frac{7+2+9+8+10}{15} =\frac{36}{15} =2.4

Therefore, the mean = 2.4
