Question:
I am unclear on how to do this. Please help.
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 0.9. You use a significance level of=0.02.
H0:p=0.9 H1:p0.9 You obtain a sample of sizen=331in which there are 305 successes. A)What is the test statistic for this sample?Round to 3 decimal places. B)What is the p-value for this sample?Round to 4 decimal places. C) Is the p-value:
less than (or equal to)
greater than
D) Does this test lead to: rejecting the null, accepting the null or failing to reject the null? E) What is the most accurate final conclusion:
- 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 0.9.
- 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 0.9.
- The sample data support the claim that the probability of a true negative on a test for a certain cancer is different from 0.9.
- 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 0.9.
