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 0.86. You use a significance level of a = 0.05.
Ho: p=0.86
H₁: p0.86
You obtain a sample of size n
=
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...
4
C
O less than (or equal to) a
O greater than a
This test statistic leads to a decision to...
O reject the null
O accept the null
O fail to reject the null

As such, the final conclusion is that....
O 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 0.86.
There is not sufficient evidence to warrant rejection of the claim that the probability of a true
