Multiple Choice

Use computer software to obtain the multiple regression equation. Use the estimated equation to find the predicted value.
-A visitor to Yellowstone National Park sat down one day and observed Old Faithful, which faithfully spurts throughout the day, day in and day out. He surmised that the height, in feet, of a given spurt was caused by the
Pressure build-up during the interval between spurts and by the momentum build-up during the duration of
The spurt. He wrote down the data to test his hypothesis. He then used the regression equation he obtained to
Predict the height of the geyser if the interval is 81 seconds and the duration is 221 seconds. $$\begin{array} { | c c c } \hline \hline \text { HEIGHT } & \text { INTERVAL } & \text { DURATION } \\\hline 150 & 86 & 240 \\154 & 86 & 237 \\140 & 62 & 122 \\140 & 104 & 267 \\160 & 62 & 113 \\140 & 95 & 258 \\150 & 79 & 232 \\150 & 62 & 105 \\160 & 94 & 276 \\155 & 79 & 248 \\125 & 86 & 243 \\136 & 85 & 241 \\140 & 86 & 214 \\155 & 58 & 114 \\130 & 89 & 272 \\125 & 79 & 227 \\125 & 83 & 237 \\139 & 82 & 238 \\125 & 84 & 203 \\140 & 82 & 270 \\140 & 82 & 270 \\140 & 78 & 218 \\135 & 87 & 270 \\140 & 70 & 241 \\100 & 56 & 102 \\105 & 81 & 271 \\\hline\end{array}$$
