Chapter 4: Q8P (page 92)

Repeat Problem 4-7 but use the values 50, 100, and 150 for the standard deviation. Superimpose all three curves on a single graph.

Short Answer

Expert verified

All three curves are plotted on the same graph. The graph is displayed below.

Step by step solution

01

Definition of standard deviation

  • The standard deviation (SD), like the average deviation, is a measure of spread around the mean.
  • Standard deviation is defined as the average deviation of data from the mean.
02

The required data for graph drawing are shown in table below.

In the table below, you'll find the information you'll need to create a graph.

Column C is for standard deviation 50

Column D is for standard deviation 100

Column E is for standard deviation 150

03

Plot the graph for light bulbs

All three curves are plotted on the same graph. The graph is displayed below.
