(a) Find the number of sensors and the number of seconds of data contained in the file. (Hint: Use the size function to help determine the number of sensors) (b) Find both the maximum value and the minimum value recorded on each sensor. Use MATLAB to determine at what times they occurred. (c) Find the mean and standard deviation for each sensor and for all the data values collected. Remember, column 1 does not contain sensor data; it contains time data.
