According to a recent U. S. Bureau of Labor Statistics report, the proportion of married couples with children in which both parents work outside the home is 59%. You select an SRS of 50 married couples with children and let p_hat =
the sample proportion of couples in which both parents work outside the home.
Using mean of 0.59 and sd of 0.0696, calculate the probability that in an SRS of 50 married couples, the proportion
of married couples in which both parents work outside the home is at least 70%.
