Question

Suppose we have a claim regarding a population proportion, p > 0.75, with a level of significance 0.05. If your test statistic is z = 0.85, what conclusion will you draw from the test?

A.

The sample data supports the claim that the population proportion is greater than 0.75.

B.

The sample data does not support the claim that the population proportion is greater than 0.75.

C.

There is not sufficient sample evidence to support the claim that the population proportion is greater than 0.05

D.

There is not sufficient data to warrant rejection of the claim that the true population proportion is greater than 0.75.

Explanation / Answer

It is right tailed test.

For level of significance 0.05, the critical value is 1.645.

Since z=0.85<1.645, we fail to reject H0.

Ans : Option C.

There is not sufficient sample evidence to support the claim that the population proportion is greater than 0.05
