In a Study of Reaction Times, the Time to Respond

Short Answer

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.

$\begin{array} { c c } \hline \text { Visual } & \text { Auditory } \\\hline 168 & 243 \\233 & 253 \\169 & 242 \\204 & 243 \\206 & 248 \\202 & 245 \\157 & 239 \\240 & 248 \\\hline\end{array}$

i). Compute a point estimate for the mean auditory response time for subjects with a visual response time of 183.
ii). Construct a 99% confidence interval for the mean auditory response time for subjects with a visual response time of 183.
iii). Predict the auditory response time for a particular subject whose visual response time of 183.
iv). Construct a 99% prediction interval for the auditory response time for a particular subject whose visual response time is 183.
