If the Lengths of Male Skis and Female Skis Are $95 \%$

question 54

Multiple Choice

If the lengths of male skis and female skis are used to construct a $95 \%$ confidence intervi for the difference between the two population means, the result is $14.32 \mathrm {~cm} < \mu _ { 1 } - \mu _ { 2 } < 21.95 \mathrm {~cm}$ , where lengths of male skis correspond to population 1 an lengths of female skis correspond to population 2. Express the confidence interval with th lengths of female skis being population 1 and lengths of male skis being population

• A) \(14.32 \mathrm {~cm} < \mu _ { 1 } - \mu _ { 2 } < 21.95 \mathrm {~cm}\)
• B) \(- 14.32 \mathrm {~cm} < \mu _ { 1 } - \mu _ { 2 } < - 21.95 \mathrm {~cm}\)
• C) \(- 21.95 \mathrm {~cm} < \mu _ { 1 } - \mu _ { 2 } < - 14.32 \mathrm {~cm}\)
• D) This cannot be determined without having the original data values.
