Question

The mean of nine observations is 36. If the mean of the first six observations is 37, then what is
the mean of the last three observations?​

Answer 1

Answer:

34

Step-by-step explanation:

Sum of 9 observations = 36×9 = 324

Sum of first 6 observations = 37×6 = 222

Remaining sum of 3 observations = 324 - 222 = 102

Mean of 3 observations = 102/3 = 34
