In a Study of Reaction Times, the Time to Respond

question 35

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.

$\begin{array} { c c } \hline \text { Visual } & \text { Auditory } \\\hline 208 & 200 \\177 & 175 \\250 & 233 \\248 & 234 \\152 & 155 \\164 & 161 \\196 & 190 \\238 & 230 \\\hline\end{array}$

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

• A) \(y = 25.345634 x\)
• B) \(y = 0.842152 + 25.345634 x\)
• C) \(y = 25.345634 + 0.842152 x\)
• D) \(y = 0.842152 x\)
