Question

If value of x for normal distribution is 35, mean of normal distribution is 65 and standard deviation is 25 then standardized random variable is

Answer 1

Answer:

standardized random variable = -1.2

Step-by-step explanation:

The standardization of a random variable.

Suppose X is a random variable with mean µ and standard deviation σ > 0. Then the standardization of X is the random variable Z = (X − µ)/σ.

X = 35

µ  = 65

σ = 25

standardized random variable  Z  =  ( 35 - 65) /25

Z = -30/25

=> Z = -1.2

standardized random variable = -1.2
