A transportation engineering study was conducted to determine the proper design of bike lanes. Data were gathered on bike-lane widths and average distance between bikes and passing cars. The data from 9 streets are 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 1.8 m, determine the corresponding minimum lane width.

ENGR 121 B Lecture Notes for 9/19/2016 Spencer Kociba Summary of Lecture: beginning to understand the vocabulary and functions in MATLAB and how we will use MATLAB and BlackBoard Learn to turn in assignments, take quizzes, etc. Goal of the course: learn to THINK like a programmer aka step by step problem solving. Problem solving techniques:...
