A transportation engineering study was conducted to determine the proper design of bike lanes. Data was gathered on bike-lane widths and average distance between bikes and passing cars. The data from 11 streets is
Distance, m | 2.4 | 1.5 | 2.4 | 1.8 | 1.8 | 2.9 | 1.2 | 3 | 1.2 |
Lane Width, m | 2.9 | 2.1 | 2.3 | 2.1 | 1.8 | 2.7 | 1.5 | 2.9 | 1.5 |
(a) Plot the data.
(b) Fit a straight line to the data with linear regression. Add this line to the plot.
(c) If the minimum safe average distance between bikes and passing cars is considered to be 2 m, determine the corresponding minimum lane width.
