A survey has been administered to random samples of respondents in each of five nations. Respondents were asked: "How satisfied are you with your life as a whole?" Responses varied from 1 (very dissatisfied) to 10 (very satisfied). For France, men had an average of 8.3 with a standard deviation of 2.2 (out of 19 males). Women had an average of 7.1 with a standard deviation of 3.7 (out of 22 females), are men and women significantly different in terms of their reported levels of satisfaction? a. Identify each of the following, using the given information. Sample Mean (Men) = Blank 1 Sample Mean (Women) = Blank 2 S1 = Blank 3 S2 = Blank 4 N1 = Blank 5 N2 = Blank 6 b. Write the null hypothesis and alternate hypothesis using statistical language. As you cannot use greek letters, in your response use "Mean 1" for X-Bar 1 and "Mean 2" for X-Bar 2. For your operations, use =, <, >, and =/= (does not equal). Null: Blank 7 Alternate: Blank 8 c. Given this is a two-sample test, you must use the t-distribution for this problem. What would be the degrees of freedom (df) for this scenario? Blank 9 d. Assume that the alpha level is 0.05. What would be the critical t-score? In other words, what t-score is our cut-off for the rejection region? Blank 10 e. Calculate the obtained z-score for this problem. Blank 11 f. Make a decision. Based on your calculations, which hypotheses would we reject? Which would we accept? (Reject Null or Accept Null? Reject Alternate or Accept Alternate?) Blank 12 Blank 1 Blank 2 Blank 3 Blank 4 Blank 5 Blank 6 Blank 7 Blank 8 Blank 9 Blank 10 Blank 11 Blank 12
