Hypothesis test for a population proportion A hospital claims that the proportion , of full-term babies born in their hospital that weigh more than 7 pounds is 40%. In a random sample of 240 babies born in this hospital, 97 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...
