A Bureau of National Affairs survey found that 79% of employers provide their workers a two-day paid Thanksgiving holiday with workers off both Thursday and Friday (USA Today, November 12, 2009). Nineteen percent of employers provide a one-day paid holiday with workers off Thanksgiving Day. Two percent of employers do not provide a paid Thanksgiving holiday. Consider a sample of 120 employers.Round your answers to four decimal places. a. What is the probability that at least 85 of the employers provide a two-day paid Thanksgiving holiday? b. What is the probability that between 90 and 100 employers provide a two-day […]
