Worksheet – Normal Distributions. 1. For each problem below draw a picture of the normal curve and shade the area you have to find. Let Z represent a variable following a standard normal distribution. (a) Find the proportion that is less than z=2.00. (b) Find the proportion that is between z = −.13 and z = 1.75.
Normal Distributions Worksheet (12-7) A set of data with a mean of 45 and a standard deviation of 8.3 is normally distributed. Find each value, given its distance from the mean. 1. +1 standard deviation from the mean 2. +3 standard deviations from the mean. 3. –1 standard deviation from the mean.
Use the area feature and the equation for the standard normal curve, y =ex^12 22/( )* ^(( )/ ). Find the area under the curve for 1.2 standard deviations from the mean.
2. Standard Normal Distribution (z-ditribution) A key tool for calculating proportions and percentages associated with normal distri-butions is the standard normal distribution. The standard normal distribution is a bell-shaped planar region bounded above by a bell-shaped curve and below by a horizontal
