collected f Suppose that a file named sensor.dat contains information set of sensors. Your instructor may provide you with this file, or need to enter it by hand from the following data 4 you nm Trime (s) Sensor 1 Sensor 2 Sensor 3 Sensor 4 Sensor 0.0000 70.6432 68.3470 72.3469 67.6751 73.1764 73.2823 65.7819 65.4822 71.8548 66.9925 64.1609 72.4888 70.1794 73.6414 72.7555 67.6970 77.4425 66.8623 80.5608 64.5008 0000 68.6878 67.2676 72.6770 63.2135 70.4300 2.7644 64.8869 59.9772 63.4028 68.7683 68.9815 75.1892 67.5346 3.5000 74.656173.315 59.7284 68.0510 72.3102 70.0562 65.7290 70.6628 63.0937 68.3950 4.5000 66.7743 63.9934 77.964771.5777 76.1828 5.0000 74.0286 69.4007 75.092177.7662 66.8436 5.5000 71.1581 69.6735 62.098073.5395 58.3739 65.0512 72.4265 69.6067 79.7869 63.8418 6.5000 76.6979 67.0225 66.5917 72.5227 75.2782 7.0000 71.4475 69.2517 64.8772 79.3226 69.4339 77.3946 67.8262 63.8282 68.3009 71.8961 8.0000 75.6901 69.6033 71.4440 64.3011 74.7210 66.5793 77.6758 67.8535 68.944459.3979 9.0000 63.5403 66.9676 70.2790 75.9512 66.7766 69.6354 63.2632 68.1606 64.4190 66.4785 1.5000 2.5000 3.0000 63.9342 65.7662 4.0000 6.0000 7.5000 8.5000 793 66 9.5000 Each row contains a set of sensor readings, with the first row containi values collected at 0 seconds, the second row containing values collected 0.5 seconds, and so on (a) Read the data file and print the number of sensors and the number 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 each sensor. Use MATLAB to determine at what times they ) Find the mean and standard deviation for each sensor and data values collected. Remember, data; it contains time data. column 1 does not contain
