I got a 2 for my typical t and 25 for the obtained t
shift For this assignment you will use the small sample formulas and Appendix B. Please see (intel Chapter 9, formulas 9.5 and 9.6 on p.232 (these are also in our Formulae Part 2.pdf in Inside blackboard) AND the supplemental document: Five Step Model for Two-Sample Test in our Week 11 folder. A survey has been administered to random samples of respondents in several countries. Respondents were asked "How satisfied are you with your life as a whole?" Responses varied from 1 to 10, with 10 indicating the highest degree of life satisfaction. You assume that the responses to the measurement of life satisfaction are realizations of a continuous variable on an interval-ratio level of measurement. You select the samples of women and men from several countries. For this assignment, you select Nigeria and want to know whether women and men in this nation are significantly different in terms of their reported levels of satisfaction. Follow our 5-step model of hypothesis testing when writing your answers. You must report Monday everything that is expected of you in each step of the model, and fully interpret your decision in Step 5 (this means three statements of your conclusion). You will set the alpha level as a=0.05 and use Appendix B to select your t(critical). 1043 women: X1 = 7.8 men: X2 = 6.7 $1 = 0.23 $2 = 0.16 N1 = 46 N2 = 42 Step 5: Make a Decision and Inter . Compare t(obtained) to t(critical) . If the test statistic, t(obtained), is in the critical region (see the blue shaded area in slide 11) Appendix B Distribution of t established by our t(critical), we reject the null hypothesis and say that the sample provides evidence in support of our research hypothesis. Use this table to find the critical region (step 3 of the five-step model) for tests . If the test statistic, t(obtained), is anywhere outs of significance with sample means when sample size (M) is small. First, choose an alpha level and a one- or two-tailed test. Then find degrees of freedom to find the critical region, we fail to reject HO and say t the t score that marks the beginning of the critical region. the sample does not support of our research hypothesis.
