### Summary Statistics for Two Independent Samples Summary statistics are given for independent simple random samples from two populations. Use the nonpooled t-interval procedure to find the 95% confidence interval. - **Sample 1** - Mean (\(\bar{x}_1\)): 73.4 - Standard Deviation (\(s_1\)): 10.9 - Sample Size (\(n_1\)): 16 - **Sample 2** - Mean (\(\bar{x}_2\)): 68.9 - Standard Deviation (\(s_2\)): 8.2 - Sample Size (\(n_2\)): 12 ### Options for the 95% Confidence Interval A. \(-1.98 \text{ to } 10.98\) B. \(-1.66 \text{ to } 10.66\) C. \(-3.34 \text{ to } 12.34\) D. \(-2.92 \text{ to } 11.92\) Please select the appropriate confidence interval based on the data provided.
