Assuming you are talking about the 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

The formula to be used is this:
x_norm = (x - x_mean)/x_std
After putting values of x, x_mean and x_std the x_norm comes out to be -1.2 which is the right answer.

Hope this cleared your doubt :blush:
