Based on their records, a hospital claims that the proportion, \( p \), of full-term babies born in the community that weigh more than 7 pounds is 43%. A pediatrician who works with several hospitals in the community would like to verify the hospital's claim. In a random sample of 250 babies born in the community, 113 weighed over 7 pounds. Is there enough evidence to reject the hospital's claim at the 0.10 level of significance? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) --- (a) Find the \( p \)-value. (Round to three or more decimal places.) \[ \text{(Answer box for \( p \)-value)} \] (b) Can we reject the claim that the proportion of full-term babies born in the community that weigh more than 7 pounds is 43%? \[ \text{O Yes} \quad \text{O No} \] --- A diagram is displayed with statistical symbols: - \(\mu, \sigma, p\) (population parameters) - \(X, s, \hat{p}\) (sample statistics) Graphs or charts are not present in the provided text.
