A hospital claims that the proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 41%. In a random sample of 150babies born in this hospital, 65 weighed over 7. pounds. Is there enough evidence to reject the hospital's claim at the 0.05level 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 he null hypothesis: H0:   The alternative hypothesis: H1:   The type of test statistic: (Choose one) Z t Chi square F             The value of the test statistic: (Round to at least three decimal places.)   The p-value: (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 than 7  pounds is 41%?   Yes

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
