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 37%. 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, 82 weighed over 7 pounds. Is there enough evidence to
reject the hospital's claim at the 0.10 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,.
H, :0
H, : 0
(b) Determine the type of test statistic to use.
D=0
OSO
Degrees of freedom: |
(c) Find the value of the test statistic. (Round to three or more decimal places.)
O<O
(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 37%?
Yes No
