Question: A story in Newsweek (14 November 1994, pp. 52-54) reported the results of a poll asking 756 American adults the question, "Do you think Clarence Thomas sexually harassed Anita Hill, as she charged three years ago?" The results of a similar poll 3 years earlier were also reported. The original poll was conducted in October 1991, during the time of congressional hearings in which Hill made allegations of sexual harassment against Supreme Court nominee Thomas. The proportion answering yes was 23% in 1991 and 40% in 1994. A 95% confidence interval for the difference in proportions answering yes in 1994 versus 1991 is 17% ± 5%. Compute and interpret the interval. Does it indicate that opinion on the issue among American adults had definitively changed during the 3 years between polls?
