Question
SCUBA divers have maximum dive times they cannot exceed when going to different depths. The
data in the table below show different depths with the maximum dive times in minutes. (Comma
separated lists of the data are also provided below the table to ease in copying the data to R.)
Depth in Feet (x)
Maximum Dive Time in Minutes (y)
50
176
60
163
70
151
80
139
90
126
100
115
x: 50, 60, 70, 80, 90, 100
y: 176, 163, 151, 139, 126, 115
1. Find the best fit line for the data.
y =
2. Graph the scatter plot of the data together with the best fit line using R. (This portion of the
problem is not graded.)
3. Predict the maximum dive time at a depth of 44 feet.
