a. To find the best estimate for the percentage of people who were affected, we need to divide the affected people by the total population and multiply by 100%. Let's see:


(224,000)/(260,000,000)\cdot100\%=0.00086\cdot100\%=0.086\%\approx0.1\%

The best estimate for the percentage of people who were affected is about 0.1%

b. To complete the statement, apply the proportion:


(224,000)/(260,000,000)=(86)/(x)

Solve for x:


\begin{gathered} 0.00086=(86)/(x) \\ x=(86)/(0.00086) \\ x=100000 \end{gathered}

Approximately 86 out of every 100,000 people in the United States were affected by the 1994 salmonella outbreak.
