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
