Question

The mean of 100 observations is 50. If one of the observation which was 50 is replaced by 150, then find the resulting mean​

Answer 1

Answer:

51

Step-by-step explanation:

Mean of 100 observations = 50

Sum of observations = 50 * 100 = 5000.

One of the observation is replaced by 150. It means 100 is added to the new sum.

Then, new sum of observations = 5000 + 100 = 5100

Resulting mean = (5100/100) = 51
