Question

If the mean of data 6,8,10,37 and m is 7 then find the value of m

Answer 1

Mean is the average of a given set of data.

Given: The mean is 7.

To find: The value of m.

Answer:

Mean = Sum of all observations/Total number of observations.

Mean: 7

Observations: 6, 8, 10, 37, m.

Sum of all observations: 6 + 8 + 10 + 37 + m = 61 + m

Total number of observations: 5

Substituting the values in the formula,

7 = 61 + m/5

7 x 5 = 61 + m

35 = 61 + m

m = 35 - 61

m = -26
