the mean of 10 observation is 3.5. if two observation namely 3.5 and 2.5 are deleted. find the new mean?

Mean of 10 observations = 3.5
So, total value of 10 observations = 3.5×10 = 35
Now, value of 2 observations deleted = 3.5 + 2.5 = 6
Therefore, new mean = mean of 8 observations = 35-68= 298 = 3.625

the new mean is 3

total value ofobservations is 35

35-7(add deleted terms)

=28

28 divided by8 as 2 no are deleted gives you 3.

thumbs up pls
