Problem 4 In a controlled laboratory experiment, scientists at the Caraga state University discovered that 22% of a certain strain of rats subjected to a 28% coffee bean diet and then force-fed a powerful cancer-causing chemical later developed cancerous tumors. Would we have reason to believe that the proportion of rats developing tumors when subjected to this diet has increased if the experiment were repeated and 21 of 48 rats developed tumors? Use a 0.1 level of significance.
