Based on their records, a hospital claims that the proportion, p, of full-term babies born weigh over 7 pounds is 47%. A pediatrician who works with several hospitals in the community would like to verify the hospital's claim and investigates. In a random sample of 210 babies born in the community, 116 weighed over 7 pounds. Is there enough evidence to reject the hospital's claim at the 0.05 level of significance? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) A. State the null hypothesis Ho and the alternative hypothesis H1. B. Find the two critical values. (Round to three or more decimal places.) C. Can we reject the claim that the proportion of full-term babies born in the hospital that weigh more than 7 pounds is 47%?
