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 48%. A pediatri who works with several hospitals in the community would like to verify the hospital's claim. In a random sample of 205 babies born in the community, 96 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 H₂ Ho p=0.48 H₁ p0.48 (b) Determine the type of test statistic to use.
