Answer 1

Step-by-step explanation:

7+14+9+12+8/total number of observation

= 7+14+9+12+8/5

=50/5

=10

Answer 2

Given:

The mean of the numbers 7, 14, 9, 12, 8.​

To Find:

The mean of the given data is?

Solution:

1. Let X1, X2, X3, .., Xn be n terms. The mean of the n terms is given by the formula,

=> Mean = (X1+X2+X3+..+Xn)/n.

2. The given terms are 7, 14, 9, 12, 8.​

=> Total number of terms = 5.

3. The Mean of the given set of data is,

=> Mean = ( 7 + 14 + 9 + 12 + 8)/5,

=> Mean = 50/5,

=> Mean = 10.

Therefore, the mean of the given set of data is 10.
