Question

According to a survey, working men reported doing 62.9 minutes of household chores a day, while working women reported tackling 76 minutes daily. But when examined more closely, millennial men reported doing just as many household chores as the average working women, 76 minutes, compared to an average of 57 minutes among both boomer men and Gen Xers. The information that follows is adapted from these data and is based on random samples of 1106 men and 805 women.
