To find the answer, we need to use the formula for the mean:
mean = (sum of all values) / (number of values)
We know that the mean is 34, and we have 6 values in the dataset. We can set up an equation:
34 = (24 + 28 + 30 + 50 + 54 + x) / 6
Multiplying both sides by 6, we get:
204 = 24 + 28 + 30 + 50 + 54 + x
Combining like terms on the right side, we get:
x + 186 = 204
Subtracting 186 from both sides, we get:
x = 18
Therefore, the missing value in the dataset is 18. The answer is A) 18.
