Question
If the value of x for normal distribution is 35, the mean of normal distribution is 65 and the standard deviation is 25, then the standardized random variable is
- -1.5
- -1.7
- -1.2
- -5
Hint:
The standardization of a random variable Suppose X is a random variable with mean µ and standard deviation σ > 0
The correct answer is: -1.2
Step 1 of 1:
We know that Z = (X −µ)/σ
now,
Use formula Z = (X −µ)/σ
