Question

16. What probability expression is equivalent to P( / z / > 1.96)?

Answer 1

Please check the explanation.

Explanation:

Given

`P(Z > 1.96)`

To determine

What probability expression is equivalent to
`P(Z > 1.96)`.

Suppose Z is a standard normal variable.

Therefore,

P(Z > 1.96) = 1 - P(Z ≤ 1.96)

solving

= 1 - Ф(1.96)

`= 1 - 0.9750`

`= 0.0250`
