Answer:
66
Step-by-step explanation:
Find the value of x in the following set of observations if their mean is 61.
45, 62, 72, X, 59, 62
Mean = Sum of all the observation /Number of observation
Sum of observations = 45 + 62 + 72 + X + 59 + 62
= 300 + X
Number of Observations = 6
Mean = 61
=> 61 = (300 + X)/6
=> 366 = 300 + X
=> X = 66
