Document Summary
Mat 121: elementary statistics and probability- lecture 13-non-standard normal. Finding probabilities: procedure, sketch a normal distribution curve, label the mean and the speci c value of x". Then shade the region that represents the probability you want: convert the speci c value of x" to a z-score using the formula, solve the problem in the standard normal case. Assume that x" is normally distributed with a mean of 10 ( =10) and a standard deviation of 4 ( =4). Find p(x <17: sketch a normal distribution curve with the labels. 1. 7 . 05 row column: use the table in your textbook. Suppose that men"s heights are normally distributed with a mean 69 inches and a standard. A boeing 747 airliner has doors with a height of 72 inches. What proportion of men can t through the door without bending: sketch a normal distribution curve with the labels. 69 72: find the corresponding z-scores x=72.
