Question

Compute the critical value z Subscript alpha divided by 2 that corresponds to a 96​% level of confidence.

Answer 1

Complete Question

Compute the critical value
`Z_{(\alpha )/(2) }` that corresponds to a 96​% level of confidence.

Answer:

The value is
`Z_{(\alpha )/(2) } = Z_{(0.04)/(2) }= 2.326`

Explanation:

From the question we are told that

The confidence level
`C = 96\%`

Generally the level of significance is mathematically represented as

`\alpha = (100 -96)\%`

`\alpha = 0.04`

Now from the normal distribution table the critical value for
`(\alpha )/(2)` is

`Z_{(\alpha )/(2) } = Z_{(0.04)/(2) }= 2.326`
