You may need to use the appropriate appendix table or technology to answer this question. The following information was obtained from independent random samples taken of two populations. \begin{tabular}{|l|l|l|} \hline & Sample 1 & Sample 2 \\ \hline Sample Mean & 48 & 42 \\ Sample Variance & 120 & 169 \\ Sample Size & 10 & 13 \\ \hline \end{tabular} The point estimate of the difference between the means is 6, the standard error is 5, and the degrees of freedom are 20. What is the 95% confidence interval for the difference between the two population means? \begin{itemize} \item -4.43 to 16.43 \item -4 to 6 \item 1 to 11 \item 3.91 to 8.09 \end{itemize}

13) An ideal Diesel cycle with air as the working fluid has a compression ratio of 18 and a cutoff ratio of 2. At the beginning of the compression process, the working fluid is at 14.7 psia, 80°F, and 117 in3. Utilizing the cold-air standard assumptions, determine (a) the temperature and pressure of air at the end of each process, (b) the net work output and the thermal efficiency, and (c) the mean effective pressure.
