1.023 × 0.5000 Ans. (b) 00174 or each of the following sets of results, calculate (1) the average, (2) the deviations, )the average deviation, (4) the relative deviations in parts per thousand, (5) the relative average deviation in parts per thousand, (6) the standard deviation by the deviation from average method, (7) the standard deviation from the range, and (8) the 95% confidence limits. (a) 35.47, 35.49, 35.42, 35.46 (b) 25.10, 25.20, 25.00 (c) 63.92, 63.75, 63.90, 63.86. 63.84 (d) 6.050, 6.048, 6.068, 6.054, 6.056 (e) 50.00, 49.96, 49.92, 50.15 Ans. (b) (i) 25.10, (3) 0.07, (5727, (6) 0.10, (7), 0.12, (8) ±0.26 5 For each set in Problem 4, calculate the Q value for the deviant result and state whether Ans. (b) 0.50; no. 6 For each set in Problem 4 for which a deviant value can be discarded, recalculate the or not the deviant value should be discarded values requested in Problem 4 after the deviant value has been discarded. ssuming that the true values are (a) 35.53, (b) 25.06, (c) 63.80, (d) 6.064, and (e) 49.80, tate whether the sets in Problem 4 are (1) both accurate and precise, (2) accurate but not precise, (3) precise but not accurate, or (4) neither accurate nor precise.
