Null Hypothesis is to test to see if all groups are the same. Alternative Hypothesis is to see if the groups are different. Read the Step by Step on pages 629-630. 8. What calculator command do you use to find the p value once you know the Chi-Squared statistic?

The MH P-value for the pooled Odds Ratio to be 1 . The Breslow-Day test for homogeneity of OR across strata. F. Assume the Pooled Mantel-Haenszel Odds-Ratio from the output holds for each strata and use this to, estimate the Within Strata Percent Risk and PAR for low birth weight from Smoking for each Racial group.

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

7. How small should the p-value be in order to claim that a result is statistically significant? The p-value needs to be as small as or smaller than the alpha, α, level. The alpha level depends on our significance level. 8. What does statistically significant mean? This means that something, an event, is unlikely to happen by chance.

df = (3 – 1)(3 – 1) = 4 ( 0.01 < P value < 0.02 (table). [P value = 0.012 (calculator).] Because P value < 0.02, we reject H0. We have strong evidence that the number of crimes committed is related to the temperature at the time of the crime. 4. A study yields a chi-square statistic value of 20 (χ2 = 20). What is the P value of the test if

What is the t test statistic and how is it interpreted? Under what conditions can this test be used… In terms of rejecting the hypothesis , how is a significance test related to a confidence interval on the same population? Use your calculator to find the p value (tcdf command) for the example Healthy Streams. What is that p-value?

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
