HW SIXTEEN

 

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 250 babies born in the community, 68 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 Ho and the alternative hypothesis H₁.
Ho :
H₁:0
(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.)
(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%?
