The standard deviation of the frequency distribution is 5.54
<h3>How to determine standard deviation?</h3>
The table of values is given as:
x f(x)
0-3 13
4-7 13
8-11 10
12-15 11
16-19 0
20-23 3
Rewrite the table by calculating the class midpoints:
x f(x)
1.5 13
5.5 13
9.5 10
13.5 11
17.5 0
21.5 3
Start by calculating the mean using:

This gives

Evaluate

The standard deviation is then calculated as:

So, we have:

Evaluate

Solve

Hence, the standard deviation is 5.54

3*2=6
2 2/3
7*2=14
2 5/7
the answer is B)
good luck
16 1/3 is bigger than 1/4
The answer to the question will be 0. 3 Modifying Above 18 with bar
<h3>What will be the decimal expansion of 7 over 22? </h3>
When we divide 7 by 22 we will get 0.3181818..........
Here 3 is not repeating but 18 is repeating again and again
So it is a Non-terminating repeating number
Thus the answers to the question will be 0. 3 Modifying Above 18 with bar
