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 47%. A pediatrician who works with several hospitals in the community would like to verify the hospital's claim. In a random sample of 190 babies born in the community, 107 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. a. State the null hypothesis H0 and the alternative hypothesis H1. b. Find the value of the test statistic. c. Find the p-value. d. Can we reject the claim that the proportion of full-term babies born in the community that weigh more than 7 pounds is 47%?
