A) For a displacement transducer having the calibration curve, y = KE, estimate the uncertainty in displacement y for E =5.00 V, if K = 10.10 mm/V with uK = ±0:10 mm/V and uE = ±0.01 V at 95% confidence.
b) The variance in the strength test values of 250 bricks is 5.83 (MN/m2)2 with a mean of 5.86 MN/m2. What is the random error in the mean value and the confidence interval at 95%.
