Asha owns a car wash and is trying to decide whether or not to purchase a vending machine so customers can buy coffee while they wait. She'll get the machine if she's convinced that more than %30, percent of her customers would buy coffee. She plans on taking a random sample of nnn customers and asking them whether or not they would buy coffee from the machine, and she'll then do a significance test using α=0.05 to see if the sample proportion who say "yes" is significantly greater than %30, percent.
