Given a random sample of 85 people attending a workshop, 63 of the respondents said the workshop was useful. What is the sample proportion of the people who said the workshop was useful?
To determine the portion of the people attending the workshop who noted that it was useful, divide the number of respondents saying it was useful by the total number. That is, 63 / 85 = 0.74 Thus, the answer is letter D.
