An Associated Press article on potential violent behavior reported the results of a survey of 750 workers who were employed full time (San Luis Obispo Tribune, September 7, 1999). Of those surveyed, 125 indicated that they were so angered by a coworker during the past year that they felt like hitting the coworker (but didn’t). Assuming that it is reason-able to regard this sample as representative of the population of full- time workers, use this information to construct and interpret a 90% confidence interval estimate of p, the proportion of all full- time workers so angered in the last year that they wanted to hit a coworker. |
