**Summary Statistics for Two Independent Samples** The table below provides summary statistics for independent simple random samples taken from two different populations. You are required to use the pooled t-interval procedure to determine the 95% confidence interval. Please round your final answer to two decimal places. - Sample 1: - Mean (\( x_1 \)): 11.4 - Standard Deviation (\( s_1 \)): 4.2 - Sample Size (\( n_1 \)): 14 - Sample 2: - Mean (\( x_2 \)): 16.7 - Standard Deviation (\( s_2 \)): 4.9 - Sample Size (\( n_2 \)): 17 **Options for the 95% Confidence Interval:** - A: \(-8.12\) to \(-2.48\) - B: \(-8.82\) to \(-1.78\) - C: \(-8.69\) to \(-1.91\) - D: \(-8.98\) to \(-1.62\)
