Water flows through a duct of square cross section as shown in Fig. P4.62 with a constant, uniform velocity of Consider fluid particles that lie along line at time Determine the position of these particles, denoted by line when Use the volume of fluid in the region between lines AB and to determine the flowrate in the duct. Repeat the problem for fluid particles originally along line CD; along line EF. Compare your three answers.

STA3032 MODULE 3 ARTICLE I. 3.1 INFERENCE FOR ONE POPULATION 1) When a population parameter is estimated by a sample statistic, this sample estimate is not 100% representative of the population because it varies from sample to sample. 3.1.1 CONFIDENCE INTERVALS 1) Confidence Interval (CI): reports an interval of plausible values based on the point estimate sample statistic and its standard deviation a. To calculate a confidence interval you first i. Select the confidence level 100(1-α)% ii. If the sample is replicated many times, the proportion of times that the CI will not cont
