Question

An organization published an article stating that in any one-year period, approximately 8.8 percent of adults in a country suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, five of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult population in the country.

a.) Calculate σx. (Round your answer to three decimal places.)

b.) Find the p-value. (Round your answer to four decimal places.)

** Is there a way to figure these on a TI-83 calculator?
