Suppose that a file named sensor. dat contains information collected from a set of sensors. Each row contains a set of sensor readings, with the first row containing values collected at 0 seconds, the second row containing values collected at 1.0 seconds and so on. Deliverables for #3:

a) Read the data file and print the number of sensors and the number of seconds of data contained in the file. (Hint: Use the size function -- don't just count the two numbers.)

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.
