Question

USA Today reported that speed skater Bonnie Blair had "won the USA's heart," according to a USA Today/CNN/Gallup poll conducted on the final Thursday of the 1994 Winter Olympics. When asked who was the hero of the Olympics, 65 percent of the respondents chose Blair, who won five gold medals. The poll of 615 adults, done by telephone, had a margin of error of 4 percent. Which of the following statements best describes what is meant by the 4 percent margin of error?

Answer 1

Answer:

The difference between the sample percentage and the population percentage is likely to be less than 4 percent

Step-by-step explanation:

The margin error is the difference between the values of the sample analyzed and the actual population. In reality, the result of the sample analyzed will be different from the actual result. This can be due to approximation error or human error. However, the difference in the two results should not be more than the allowable limit.
