According to a dental association, 66% of all dentists use nitrous oxide (laughing gas) in their practice. In a random sample of 750 dentists, let p represent the proportion who use laughing gas in practice. Complete parts a through d below. a. Find E (p). E (P) =[ b. Find 6. 0₁ p (Round to two decimal places as needed.) (Round to four decimal places as needed.) c. What does the Central Limit Theorem say about the shape of the sampling distribution of p? C OA. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will become approximately normal. OB. The Central Limit Theorem says that the shape of the sampling distribution of p is completely determined by the population parameter p. OC. The Central Limit Theorem does not say anything about the sampling distribution of p because it is not a population mean. OD. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will approach the population distribution. d. Find P (p>0.55). P(p>0.55) = (Round to three decimal places as needed.)
