(choose chapter or problem)

The article “Tibiofemoral Cartilage Thickness Distribution and its Correlation with Anthropometric Variables” (A. Connolly, D. FitzPatrick, et al., Journal of  Engineering in Medicine, 2008:29–39) reports that in a sample of 11 men, the average volume of femoral cartilage (located in the knee) was \(18.7 \mathrm{~cm}^{3}/) with a standard deviation of

\(3.3 \mathrm{~cm}^{3}\) and the average volume in a sample of 9 women was \(11.2 \mathrm{~cm}^{3}\) with a standard deviation of \(2.4 \mathrm{~cm}^{3}\). Find a \(95 \%\) confidence interval for the difference in mean femoral cartilage volume between men and women.
