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 195 babies born in the community, 98 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.) р o a р (a) state the null hypothesis H, and the alternative hypothesis Hi- H : X| s <a H:0 . 8 (b) Determine the type of test statistic to use. (Choose one) O=D OSO DO (c) Find the value of the test statistic. (Round to three or more decimal places.) ロロ O<O D> х $ ? (d) Find two critical values. (Round to or more decimal places.) and | (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 O NO
