Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. Suppose that 40% of all supermarkets in the US use recyclable plastic bags. We would like to assess if the proportion of supermarkets in Michigan that use recyclable plastic bags is more than the stated rate. For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. H0: Ha: The parameter p represents ___(provide appropriate definition in context)________
