During an experiment, an aerospace engineering student measures a wind tunnel's velocity N times. The student reports the following information, based on 90% confidence, about the finite data set: mean velocity=25 m/s, velocity standard deviation=1.5 m/s, and uncertainty in velocity = +- 2.61m/s. Determine N the standard deviation of means based upon this data set (m/s) the uncertainty at 95% confidence, in the estimate of the true mean value of the velocity in m/s the interval about the sample mean over which 50% of the data in this set will be (m/s)
