Based on their records, a hospital claims that the proportion, p, of full-term babies born in the community that weigh more than 7 pounds is 38%. A pediatrician who works with several hospitals in the community would like to verify the hospital's claim. In a random sample of 165 babies born in the community, 52 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. H₁ : Ho H₁ : ☐ (b) Determine the type of test statistic to use. (Choose one) (c) Find the value of the test statistic. (Round to three or more decimal places.) 0 (d) Find the p-value. (Round to three or more decimal places.) μ Χ ロ=ロ OO b S □□ р □<□ □>□ G (e) Can we reject the claim that the proportion of full-term babies born in the community that weigh more than 7 pounds is 38%? O Yes No
