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) 50 60 70 80 90 100 x: 50, 60, 70, 80, 90, 100 y: 179, 166, 150, 138, 124, 110 Maximum Dive Time in Minutes (y) 179 166 150 138 124 110 1. Find the best fit line for the data. y = + x 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 23 feet. Question Help: D Post to forum
