Question

You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.33. You use a significance level of α=0.10α=0.10.

H0:p=0.33H0:p=0.33
H1:p≠0.33H1:p≠0.33

You obtain a sample of size n=180n=180 in which there are 39 successes.

What is the test statistic for this sample? (Report answer accurate to two decimal places.)
test statistic =

What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =

The p-value is...

less than (or equal to) αα
greater than αα

This test statistic leads to a decision to...

reject the null
accept the null
fail to reject the null

As such, the final conclusion is that...

There is sufficient evidence to warrant rejection of the claim that the probability of a true negative on a test for a certain cancer is different from 0.33.
There is not sufficient evidence to warrant rejection of the claim that the probability of a true negative on a test for a certain cancer is different from 0.33.
The sample data support the claim that the probability of a true negative on a test for a certain cancer is different from 0.33.
There is not sufficient sample evidence to support the claim that the probability of a true negative on a test for a certain cancer is different from 0.33.
