MyLab Problem 5.1.49-T Probability Models

MyLab: 8.1.App1 and 8.1.App2 Use StatCrunch Applet: Applets > Sampling Distributions Distribution of the Sample Mean

ILLUSTRATE THE MEANING OF LEVEL OF CONFIDENCE

Population proportion of F0 tornadoes: 0.432

Obtain a simple random sample of 60 tornadoes.

REPEAT THIS PROCESS MANY TIMES (APPLET)
