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 3. -1 standard deviation from the mean Sketch a normal curve for each distribution. standard deviations from the mean.
Worksheet 3 for Wed., Sept. 16: Normal Distributions. Practice using the standard normal table to find the following. In each case sketch the area that you are looking for under the standard normal curve drawn.
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
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.
• be able to use tables of the normal distribution to solve problems; • be able to use the normal distribution as an approximation to other distributions in appropriate circumstances.
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.
