Suppose that a fi le named sensor.dat contains information collected from a set of sensors. Your instructor may provide you with this fi le, or you may need to enter it by hand from the following data:

Each row contains a set of sensor readings, with the fi rst row containing values collected at 0 seconds, the second row containing values collected at 1.0 seconds, and so on.
(a) Read the data fi le and print the number of sensors and the number of seconds of data contained in the fi le. ( 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.
