Question

There is one more number in that pic. 12.3 is the number

Find the mean and range​

Answer 1

Answer:

Here it goes.....

Step-by-step explanation:

Mean is the total sum divided by the total no. of elements :

So mean, M = (13.2+14.5+12.9+13.9+15.6+14.2+12.3) / 7

=96.6 / 7

=13.8

So mean is 13.8

Range is the difference between the largest and the smallest values :

So Range , R = 15.6 - 12.3

= 3.3

So range is 3.3
