Question

A two-tailed test is being done. The distribution is normal and the significance level is 5%. What are the critical values?

math Statistics-And-Probability

Answer 1

Answer #1

Significance level ( $alpha$ ) is 0.05

The test is two tailed therefore critical value is on both side of the distribution.

$Zalpha/2 = Z$ 0.05/2 $= Z$ 0.025 $士1 .960$

Using Z table.

The critical values is $±1.960$

True or False? For a two-tailed test using z values at the .05% significance level we reject H0 if z ≤ -1.960 or if z ≥ 1.960. Take a look at the specific number used for significance level. It is asking for a 0.05% significance level which would equate to 0.005 not 0.05. This answer should be false than correct? Because if it was asking for a 5% significance level than it would be true. In this case it is...
