A chemical manufacturer claims that its ice-melting product will melt snow and ice at temperatures as low as 0◦ Fahrenheit. A representative for a large chain of hardware stores is interested in testing this claim. The chain purchases a large shipment of 5-pound bags for distribution. The representative wants to know, with 95% confidence and within ±0.05, what proportion of bags of the chemical perform the job as claimed by the manufacturer. How many bags does the representative need to test? What assumption should be made concerning the population proportion? (This is called destructive testing; that is, the product being tested is destroyed by the test and is then unavailable to be sold.) The population proportion should be assumed to be equal to ________+_ . (Round to four decimal places as needed.)
