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. $$\begin{array} { | c c c } \hline \hline \text { HEIGHT } & \text { INTERVAL } & \text { DURATION } \\\hline 150 & 86 & 240 \\154 & 86 & 237 \\140 & 62 & 122 \\140 & 104 & 267 \\160 & 62 & 113 \\140 & 95 & 258 \\150 & 79 & 232 \\150 & 62 & 105 \\160 & 94 & 276 \\155 & 79 & 248 \\125 & 86 & 243 \\136 & 85 & 241 \\140 & 86 & 214 \\155 & 58 & 114 \\130 & 89 & 272 \\125 & 79 & 227 \\125 & 83 & 237 \\139 & 82 & 238 \\125 & 84 & 203 \\140 & 82 & 270 \\140 & 82 & 270 \\140 & 78 & 218 \\135 & 87 & 270 \\140 & 70 & 241 \\100 & 56 & 102 \\105 & 81 & 271 \\\hline\end{array}$$

Definitions:

Real Lower Limits

The actual start point of a class interval in statistics, indicating the smallest value that can be included in that interval.

Particular Level

A specific value or category of a variable within a research or statistical analysis.

Grouped Frequency Distribution

A representation of data that shows the number of observations within a given interval, helping in understanding the distribution of data points.

Equal Size
