Based on their records, a hospital claims that the proportion, p, of full-term babies born weigh over 7 pounds is 46%. 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, 52 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. Would (Z) (t) (Chi-square) or (F) be the best statistic to use? C. Find the value of the test statistic. (Round to three or more decimal places.) D. Find the two critical values. (Round to three or more decimal places.) E. Can we reject the claim that the proportion of full-term babies born in the hospital that weigh more than 7 pounds is 46%? (Yes or no)
