Question
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly less than 0.83. You use a significance level of α=0.01α=0.01.
H0:p=0.83H0:p=0.83
H1:p<0.83H1:p<0.83
You obtain a sample of size n=747n=747 in which there are 610 successes.
What is the test statistic for this sample? (Report answer accurate to three 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 less than 0.83.
- 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 less than 0.83.
- The sample data support the claim that the probability of a true negative on a test for a certain cancer is less than 0.83.
- 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 less than 0.83.
