If the lengths of male skis and female skis are used to construct a 95% confidence interval for the difference between the two population means, the result is 14.32 cm < μ1 - μ2 < 21.95 cm, where lengths of male skis correspond to population 1 and lengths of female skis correspond to population 2. Express the confidence interval with the lengths of female skis being population 1 and lengths of male skis being population
