Last updated: 7/31/2022

Conduct a hypothesis testing to the claim about a population proportion. A supplier of digital memory cards claims that no more than 1% of the cards are defective. In a random sample of 500 memory cards, it is found that 2% are defective, but the supplier claims that this is only a sample fluctuation. At the 0.01 level of significance, test the supplier's claim that no more than 1% are defective.
