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 45%. A pediatrician who works with several hospitals in the community would like to verify the hospital's claim. In a random sample of 250

babies born in the community, 134 weighed over 7 pounds. Is there enough evidence to reject the hospital's claim at the 0.01 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 H0 and the alternative hypothesis H1.
H0:
H1:
(b)	Determine the type of test statistic to use.
	(choose one) (Z, t, Chi-Square, F)
(c)	Find the value of the test statistic. (Round to three or more decimal places.)
(d)	Find the p-value. (Round to three or more decimal places.)
(e)	Can we reject the claim that the proportion of full-term babies born in the community that weigh more than 7 pounds is 45%?
Yes No
