A hospital claims that the proportion, p, of full- term babies born in their hospital that weigh more than - pounds is 48%. In a random sample of 175 babies born in this hospital, 6s weighed over , pounds. Is there enough evidence to reject the hospital's claim at the o0os level of significance? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) (a) State the null hypothesis H, and the alternative hypothesis H,. O P H, :0 H, :0 (b) Determine the type of test statistic to use. (Choose one) D=0 OSO (c) Find the value of the test statistic. (Round to three or more decimal places.) ? (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 their hospital that weigh more than 7 pounds is 48%? OYes ONo
