QuestionQuestion 9 of 10 (i) point) I Question Attempt 2 of Unilmied
Fast reactions: In a study of reaction times, the time to respond to a visual stimulus $(x)$ and the time to respond to an auditory stimulus ( $y$ ) were recorded for each of 8 subjects. Times were measured in thousandths of a second. The results are presented in the following table. \begin{tabular}{cc} \hline Visual & Auditory \\ \hline 191 & 169 \\ 203 & 206 \\ 201 & 197 \\ 188 & 193 \\ 228 & 209 \\ 161 & 159 \\ 176 & 163 \\ 178 & 201 \\ \hline \end{tabular} Send data to Excel
The least-squares regression line $\hat{y}=b_{0}+b_{1} x=46.9658+0.7348 x$ and $\Sigma(x-\bar{x})^{2}=2915.5000$ are known for this data. Construct a $95 \%$ confidence interval for the slope. Round the answers to at least four decimal places.
