An article in the newspaper claims that 60% of registered drivers have the organ donor designation on their driver's license. A researcher at a hospital decides to investigate this claim. The researcher selects a random sample of 50 registered drivers and finds that 44.0% have the organ donor designation on their driver's license. Do the data provide convincing evidence at the ?α = 0.05 level that fewer than 60% of registered drivers have the organ donor designation on their license?
The supply management of a certain company suggested adopting the water-on-demand system in restaurants on a certain island, in order to conserve water. A restaurant owner stated that 30% of customers do not drink water, and therefore water conservation would be due not only to the water not drunk in each glass, but also to the water saved by washing the glasses. Suppose a sample of 480 restaurant patrons indicated that 128 do not drink water. Test the restaurant owner's claim at the 0.05 level of significance.
