The mean and standard deviation for the sample of adult returnees with adolescent children in Israel (N = 1,012) on the adolescent-parent relationship stress index were 82.65 points and 18.70 points, respectively.

The mean and standard deviation for the sample of adult non returnees with adolescent children in Israel (N = 620) were 75.54 points and 16.87 points, respectively.

The American norm for the index is 85.20.

Do non-returnee Orthodox Jews with adolescent children in Israel tend to report less adolescent-parent relationship stress than the American norm? Answer the question by using the information provided above and conducting a one-sample t test. Give the null and research hypotheses, calculate the appropriate test statistic and its associated degrees of freedom, identify the decision rule, indicate your decision and on what it is based, and interpret the result. Use a rejection level or alpha of .01. Show your work, rounding at each calculation to the third decimal place. Use the outline below to organize your answer.
