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 210 babies born in the hospital, 102 weighed over 7 pounds. Is there enough evidence to reject the hospital's claim at the 0.5 level of significance? a. State the null hypothesis H0 and the alternative hypothesis H1. b.Determine the type of test statistic to use c. Find the value of the test statistic. Round to three or more decimals. d. Find the p-value (round to three decimal places) e. Can we reject the claim that the proportion of full-term babies born in the community that weigh more than 7 pounds is 41%?

Question

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 210 babies born in the hospital, 102 weighed over 7 pounds. Is there enough evidence to reject the hospital's claim at the 0.5 level of significance?

a. State the null hypothesis H0 and the alternative hypothesis H1.

b.Determine the type of test statistic to use

c. Find the value of the test statistic. Round to three or more decimals.

d. Find the p-value (round to three decimal places)

e. Can we reject the claim that the proportion of full-term babies born in the community that weigh more than 7 pounds is 41%?
