Based on their records, a hospital claims that the proportion, p, of full-term babies born weigh over 7 pounds is 36%. 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 145 babies born in the community, 49 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 H₁. Ho :D 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.) 0 (d) Find the two critical values.
