An article in the Annals of the Association of American Geographers (June 1992) revealed that only 133 of 337 randomly selected residences in Los Angeles County were protected by earthquake insurance.
-What are the appropriate null and alternative hypotheses to test the research hypothesis that less than 40% of the residents of Los Angeles County were protected by earthquake insurance?
-Do the data provide sufficient evidence to support the research hypothesis, using alpha=0.10
-Calculate the p-value for the test.
The solution is attached in Word as a 186 explanation of how to calculate a p-value and decide if evidence sufficiently supports a hypothesis.
