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 235 babies born in this hospital, 102 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 fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. The null hypothesis: H0: The alternative hypothesis: H1: The type of test statistic: (Choose one)ZtChi squareF The value of the test statistic: (Round to at least three decimal places.) The two critical values at the 0.01 level of significance: (Round to at least three decimal places.) and Can we reject the claim that the proportion of full-term babies born in their hospital that weigh more than 7 pounds is 35% ?
