Q.4. two thermocouples (temperature measurement devices) are tested by inserting their probes in boil- ing water, recording the readings, removing and drying the probes, and then doing it again. the results of five measurements are as follows: t(°c)-thermocouple a | 72.4 | 73.1 | 72.6 72.8 | 73.0 t(c) thermocouple b 973 1014 98.701100.4 (a) for each set of temperature readings, calculate the sample mean, the range, and the sample (b) which thermocoupie readings exhibit the higher degree of scatter? which thermocouple is more standard deviation. accurate?
