Transcribed Image Text:### 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.
