b. What should the null and alternative hypotheses? State each hypothesis using both words and statistical symbol notation. (2 points total. 1 for each hypothesis: .5 for written, .5 for notation) c. Calculate standard error (SE, which is the standard deviation of the sampling distribution) (1 point total: .5 if the process is correct but the result was calculated incorrectly) d. Calculate the Z statistic (which indicates where our sample mean is located on the sampling distribution) (1 point total: .5 if the process is correct but the result was calculated incorrectly) e. Determine the critical 2 value(s). Explain how you nd the answer. (1 point: .5 for the 2 value, .5 for the rationale, deduct .5 if only one 2 value is mentioned) f. Compare the 2 statistic with the appropriate critical 2 value and then draw a conclusion about the result of the hypothesis test. What is the answer to the research question now? - Do you "reject\" or \"fail to reject" the null hypothesis? (.5 point) - What is the answer to the research question? (.5 point) g. Calculate the standardized effect size. (1 point: deduct .5 if the process is correct but the result was calculated incorrectly) Answer the following questions based on this alternative scenario: Because a sample of 100 people is small, it may not represent the state of Arizona adequately. So the researcher decides to continue to collect data until the sample becomes 400. The average life expectancy remains 79.7, the same as the previous scenario. All other aspects of the study remain unchanged. h. What is the standard error with this sample? (1 point: deduct .5 if the formula is correct but the calculation is incorrect)
