A temperature sensor having a range of 0-100°C has a worst case accuracy specification of ± 1.0% of true value of ± 0.3% of full scale, whichever is higher. The sensitivity of the sensor is experimentally obtained by taking its readings at true temperatures 25°C and 75°C. The maximum error in sensitivity, expressed as percentage of its ideal value is
Direction: It consists of two statements, one labeled as ‘Statement (I)’ and the others as ‘Statement (II)’. You are to examine these two statements carefully and select the answer using the codes given below:Statement (I): For random error with Normal distribution, probable error = ± 0.6745 σ, where σ is the standard deviation.Statement (II): Probable error ξρ is that error value where there is a 50% chance that any observation has a random error no grater than ± ξρ
