Question
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 36%. A pediatrician who works with several hospitals in the community
would like to verify the hospital's claim. In a random sample of 180 babies born in the community, 46
weighed over 7 pounds. Is there enough evidence to reject the hospital's claim at the 0.01 level of
significance?
Expahel
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.
H : 0
H, :0
(b) Determine the type of test statistic to use.
O-0 OSO
(Choose one) ▼
(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 36%?
