4) The number of cars passing through the intersection of Lexington rd and Hw 77 was counted for six weeks during the Fall semester. The data is found in the traffic.xlsx. a. Use a loop to determine how many times the number of cars passing through the intersection increased from day to day and was greater than 1400. ex) The number of cars passing through on the first Thursday is greater than 1400 (it is 1465) and it is greater than the day before (1123). b. Use a loop to find the average number of cars passing through the intersection each week. You may use MATLAB's mean function. Store the averages in a vector. 4) The number of cars passing through the intersection of Lexington rd and Hw 77 was counted for six weeks during the Fall semester.
