95% confidence interval Are middle class families more likely than working class families to maintain contact with kin? write a paragraph summarizing the results of these tests. a. A sample of 89 middle class families reported an average of 7.3 visits per year with close kin with standard deviation of 0.3 while a sample of 55 working class families averaged 8.2 visits with a standard deviation of .05. Is this difference significant? b. The middle class families averaged 2.3 phone calls (sd of .05) and 8.7 emails (sd of 0.3) per month with close kin. The working class families averaged 2.7 calls (sd of 0.8) and 5.7 emails (sd of 1.1) per month. Are these differences significant?
