What is the null hypothesis? 2. What is the alternative hypothesis? 3. What is the risk level? A 0.25B. 0.5C. 0.01D. 0.05 4. What is the best statistical test to use? A. t-Test for independent samplesB. correlation testC. ANOVAD. z-testE. t-Test for dependent samples 5. Compute the test statistic. Also, remember to use the variance rather than the standard deviation in your calculation. Put ur calculated t value below, round your answer to two decimal places: Image transcription text(mi -m2) ( 1) (12-1)$5(m-ng) 6. Now it’s time to compare our obtained value (the one you just calculated) to the critical value. First, we’ll need the degrees of freedom. What are the degrees of freedom? A. 28B. 19C. 40D. 30 7. Should we use a “one tailed” or a “two tailed” test for this?PS. To figure this out, think about whether it is directional or non-directional. look at ur alternative hypothesis (above!), and think about the prompt for the assignment—did we expect there to be more sacks in one group than the other or were simply testing whether they were different?A. two tailedB. one tailed 8. What is the critical value for this statistical test? PS: you’ll need your answers to the previous two questions, as well as your “level of risk”; remember, if the exact degrees of freedom aren’t in the t-test table of critical values, you can choose the closest value that is there). A. 2.043B. 2.049C. 1.701D. 1.562 9. Put ur results as you would see it in a results section of an empirical research paper A P A (F O R M A T ) Make sure to include the means and Standard Devations. 10. Based on your answer to the previous question, what is your decision? A. Reject the null hypothesisB. Fail to reject the null hypothesisC. Not enough information to decide 11. Imagine that you also wanted to compare if there was a difference in the number of touch towns scored between the NFC and AFC. You write up the following results: An independent samples t-Test comparing the average number of touchdowns scored during the regular season between the NFC and AFC was statistically significant, t(30) = 1.92, p < .05. The number of touchdowns scored by the teams in the AFC (M = 25.125, SD = 7.54) than the NFC (M = 22.25, SD = 2.54.Calculate the effect size for this new t-test, using the Pooled Variance Formula (Below). Round your answer to two decimal places. ES=(m1−m2)(σ12+σ22)2 Image transcription textES (m1 -m2)12. What "size" is this effect size? A. There isn't enough information to answer this question.B. MediumC. SmallD. Large MathStatistics and ProbabilityMAR 1931Share Question
