A new credit card company is investigating various market segments to determine whether it is profitable to direct its advertising specifically at each one. One of the market segments is composed of Hispanic people. The latest census indicates that there are 31,669,000 Hispanic adults (18 and over) people in the United States. A survey of 475 Hispanics asked each how they usually pay for products that they purchase. The responses are:

1. Cash

2. Check

3. Visa

4. MasterCard

5. Other credit card

Estimate with 95% confidence the number of Hispanics in the United States who usually pay by credit card.
