Find the mean of the ever number between 50 and 70.​

Answer»

Step-by-step explanation:

Total EVEN NUMBERS between 50 and 70 are 11

MEAN = sum of all observations/total no. Of observations

Here.. Total no. Of observations are 11

And observations are.... 50,52,54,56,58,60,62,64,66,68,70

Sum of observations=660

660/11

=60

Therefore,mean even numbers between 50 and 70 are 60
