For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. How hard is it to reach a businessperson by phone? Let \( p \) be the proportion of calls to businesspeople for which the caller reaches the person being called on the first try. **(a)** If you have no preliminary estimate for \( p \), how many business phone calls should you include in a random sample to be 80% sure that the point estimate \( \hat{p} \) will be within a distance of 0.03 from \( p \)? (Round your answer up to the nearest whole number.) - **457** phone calls **(b)** A report states that businesspeople can be reached by a single phone call approximately 15% of the time. Using this (national) estimate for \( p \), answer part (a). (Round your answer up to the nearest whole number.) - **393** phone calls
