Question

Find the standard deviation of first 10 even integer

Answer 1

Answer:

Step-by-step explanation:

First 10 even integers are : 2 4 6 8 10 12 14 16 18 20

N = 10; total no.

Mean = (2+4+6+8+10+12+14+16+18+20)/10 = 11.1

X Y  Mean(u) (Y-u)   (Y-u)^2

1 2 11.1        -10.1 102.01

2 4         -9.1 82.81

3 6         -8.1 65.61

4 8          -7.1 50.41

5 10         -6.1 37.21

6 12         -5.1 26.01

7 14        -4.1 16.81

8 16        -3.1 9.61

9 19        -2.1 4.41

10 20         -1.1 1.21

By using the formula of standard deviation we get;

Standard Deviation = 6.293
