Based on their records, a hospital claims that the proportion, p, of full-term babies born weigh over 7 pounds is 44%. A pediatrician who works with several hospitals in the community would like to verify the hopital's claim and investigates. In a random sample of 130 babies born in the community, 41 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.

Question
Based on their records, a hospital claims that the proportion, p, of full-term babies born weigh over 7 pounds is 44%. A pediatrician who works with several
hospitals in the community would like to verify the hopital's claim and investigates. In a random sample of 130 babies born in the community, 41 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 H, and the alternative hypothesis H,.

(c) Find the value of the test statistic. (Round to three or more decimal places.)
O<O
(d) Find the two critical values. (Round to three or more decimal places.)
