An American Express survey of small-business owners found that 71% of female owners feel stressed by their work/life balance, compared to 62% of their male counterparts. Assume that file XR11063 contains the underlying sample data for female and male smallbusiness owners, respectively, with the data coded so that 1 = feels no stress in work/life balance and 2 = feels stress in work/life balance. Using the 0.01 level of significance, evaluate the null hypothesis that female and male small-business owners might really be equally likely to feel stress in their work/life balance. Identify and interpret the p-value for the test, then construct and interpret the 99% confidence interval for the difference between the population proportions.
