A hospital claims that the proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 35%. In a random sample of 160 babies born in this hospital, 54 weighed over 7 pounds. Is there enough evidence to reject the hospital's claim at the 0.05 level of significance? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) The null hypothesis: H, : 0 The alternative hypothesis: H, : The type of test statistic: (Choose one) D>O The value of the test statistic: (Round to at least three decimal places.) The two critical values at the 0.05 level of significance: and | (Round to at least three decimal places.) Can we reject the claim that the proportion of full- term babies born in their hospital that weigh more Yes No than 7 pounds is 35%? a.
