3. A researcher is testing a two-tailed null hypothesis at the p < .01 level with df = 45. What critical value would she or he use? Justify your answer
A researcher who wants to know whether the proportion of male births in a hospital is different from the established baseline of 51.07%, would like to test the following hypotheses:
Ho:P = 0.51 vs. Ha :P = does not equal 0.51
a) Is the alternative hypothesis upper tail, lower tail, or two tailed?
b) What do you conclude if the test results p-value of 0.03 at alpha value = 5%
c) What do you conclude if the test results p-value of 0.08 at alpha value = 10%
You complete a hypothesis test using alpha = .05 and based on the evidence from the sample, your decision is to fail to reject the null hypothesis. If the treatment actually does have an effect, which of the following is true?

Since the p-value is less than alpha, you do not reject the null hypothesis C. Since the p-value is larger than alpha, you reject the null hypothesis. D.
