N: 1-proportion z-test. T: O: p-value = .10 M: Retain the null hypothesis. S: We do not have enough statistical evidence, p-value of .10 at , to reject the null hypothesis. We must retain the null hypothesis that the screening test for prostate cancer successfully detects cancer is 85% of patients with prostate cancer.

We computed the test statistic to be ~2.95. And the critical value or a 1 tail upper at 1% is 2.33 . And the p-value for a 1-tail “upper” test is .001609866. Conclusion: Since our p-value is

Be able to calculate the test statistic, which is a z-value in this case. Be able to compute the P-value and be able to write out the probability statement for the P-value that involves the test statistic. Be able to determine whether or not the null hypothesis should be rejected. 6.4 Small-Sample Test for a Population Mean

Most answers were straight from calculator (ok) Some students reported numerator and denominator of test statistic separately, with appropriate graph, but did not report test statistic. Some students only reported the p-value, not test statistic (not common) or d.f. Component 4: Conclusion: Most students drew the correct conclusion

power (of a test) Calculator Skills: ZInterval. Z-Test 11.1 Tests of Significance. What is a null hypothesis? What is an alternative hypothesis? In statistics, what is meant by the P-value? If a P-value is small, what do we conclude about the null hypothesis? If a P-value is large, what do we conclude about the null hypothesis?
