In a Study of Reaction Times, the Time to Respond $( x )$

question 2

Multiple Choice

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.
$\begin{array}{cc}\hline \text { Visual } & \text { Auditory } \\\hline 218 & 209 \\153 & 150 \\240 & 226 \\202 & 196 \\243 & 225 \\165 & 161 \\207 & 196 \\209 & 198 \\\hline\end{array}$

Compute the least-squares regression line for predicting auditory response time $( y )$ from visual response time $( x )$ .

• A) \(y = 20.509336 x\)
• B) \(y = 20.509336 + 0.853345 x\)
• C) \(y = 0.853345 x\)
• D) \(y = 0.853345 + 20.509336 x\)
