In a study of marital satisfaction, a random sample of 12 couples married for between five and fifteen years was obtained. Each couple was interviewed by the researcher and rated on a Marital Cohesion (MC) scale. MC MC2 14 196 9 81 7 49 14 196 15 225 13 169 10 100 17 289 11 121 18 324 14 196 14 196 Σ- 156 Σ(x2 ) -2142 %D A. What is the mean of Marital Cohesion? 1/2 B. What is the standard deviation of Scores for hypothesis testing? (Round to the nearest hundredths) C. Is there a significant difference between the sample mean of scores and the population mean of 15? Carry out all 9 steps of the hypothesis testing.
