Extracted text: Q2/ A: The volumetric flow rate of a process fluid, V (cm'/s), is measured five times, with the following results: Measurement V(em'/s) 2. 4 5 232 248 227 241 239 a. Calculate the sample mean, range, sample variance and sample standard deviation. b. There is a high probability (above 90% ) that a measured value of (V) will fall within two standard deviations of the mean. Report the value of (V) in the form V = atb. choosing the values of (a) and (b) to define this range.
