the question of this answer
Step-by-step explanation:
mean
the sum of observation divide by total no of observation is the formula for mean
now
if we will find sum for the observation we will get 545
now we will divide 545 by total no of observation according to the formula
now total no of observation =25
sum of observation = 545
