Identify the null hypothesis, alternative hypothesis, P-value, conclusion about the null hypothesis, and final conclusionthat addresses the original claim.9. A supplier of digital memory cards claims that no more than 1% of the cards are defective. In a random sampleof 500 memory cards, it is found that 3% are defective, but the supplier claims that this is only a samplefluctuation. At the 0.05 level of significance, test the supplier's claim that no more than 1% are defective.

From the given information, the claim of the problem is the percentage of defectives is no more than…

If the null hypothesis is true, which of the following statements is a correct interpretation of the pp-value? Of all possible samples of the same size, 40.58 percent will result in 85 percent of adult sea turtles on the beach being female.
