100 velocity measurements are taken in a wind tunnel. The sample mean velocity is V=5.126 m/s The sample standard deviation of all the readings is 0.0690 m/s We assume that the errors in the readings are purely random (a) Calculate the probability that the velocity of a random measurement is in the range 5.126 m/s <V < 5.200 m/s. In other words, calculate P(5.126 < V <5.200). (b) Calculate the probability that the velocity of a random measurement is in the range 5.000 m/s<V < 5.200 m/s. In other words, calculate P(5.000 < V <5.200). 100 velocity measurements are taken in a wind tunnel.
