Amy works for a company that produces plastic lids and cups for restaurants. She wants to use a one-sample z interval to estimate what proportion of lids produced in a day have a defect that makes them not fit the cups. She takes a random sample of 100 lids from the more than 1000 total lids produced that day and finds 5 lids in the sample with this defect. Which conditions for constructing this confidence interval did Amy's sample meet?
