**Determine the critical value for a right?-tailed test regarding a population proportion at the alpha?equals=0.05 level of significance.**

Determine the critical value for a right-tailed test regarding a population proportion at the alpha?equals=0.05 level of significance.

**Answer**

Step 1 of 2:

We have the population proportion at = 0.05 level of significance.

The claim is to find the critical value.

Step 2 of 2:

Critical it is a line on a graph that splits the graph into two parts.

Critical value for right tailed test is

t1 - a = t1 - 0.05

= t0.95

From the area under normal curve table, we have to check for the value 0.95

The value 0.95 lies in the 1.6th row and between 4th and 5th column.

Then t0.95= 1.645

Hence, the critical value for = 0.05 level of significance is 1.645.
