12. What is the p-value you obtained using the theory based test? 13. What is the standardized statistic? 14. Do the results of the theory-based test support the conclusion you made earlier? Explain why. 15. Do you feel comfortable generalizing your results to all people? If so, why? If not, what would you have done differently to ensure that you would feel comfortable generalizing and to what population? 16. What research question would suggest a two-sided test instead? 17. What would the hypothesis statements be under a two-sided test? 18. Perform a two sided-test using simulation. Describe exactly how you use the applet to do so. 19. What is the p-value you obtain? 20. Comparing the two-sided p-value to the one-sided p-value you obtained earlier, what is the expected characteristic of the two-sided p-value? That is, is the two-sided value what you should have expected it would be? 21. Calculate a 95% confidence interval by hand using the 250 method. 22. What value is the center of your confidence interval? 23. What is meant by the margin of error
