To avoid modeling the physical characteristics of wheel encoders such the square wave outputs, it is desirable to generate encoder readings based on probabilities. For this case, the wheel speed estimated by the encoder will be the true speed value with noise added according to some probability distribution function to represent the uncertainty associated with the sensors. Propose a suitable probability distribution function for generating encoder estimates from the actual velocity values. Clearly state all assumptions.

A Statistics class is estimating the mean height of all female students at their college. They collect a random sample of 36 female students and measure their heights. The mean of the sample is 65.3 inches. The standard deviation is 5.2 inches. What is the 90% confidence interval for the mean height of all female students in their school? Assume that the distribution of individual female heights at this school is approximately normal? (56.5, 74.1) (63.6, 67.0) (63.8, 66.8) (63.9, 66.7) Question 3
