Question

The value of the cumulative standardized normal distribution at 1.5x is 0.9332. the value of x is

Answer 1

Use the table of standardized normal cumulative function.

Look up the corresponding x' for the value z=0.9332: I found x'=0.8232 (approximately).

We know that x'=1.5x, so x = 0.8232/1.5 = 0.5488

Answer 2

The value of "x" will be "0.5488".

According to the question,

• z = 0.9332

By using the standardized normal cumulative function,

• $x' = 0.8132$

We know,

→ $x' = 1.5 x$

then,

→ $x = \frac{x'}{1.5}$

By substituting the value, we get

      $= \frac{0.8232}{1.5}$

      $= 0.5488$

Hence, the above answer is appropriate.
