A Bureau of National Affairs survey found that 79% of employers provide their workers with a two-day paid Thanksgiving holiday with workers off both Thursday and Friday. 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. What is the probability that less than 20 of the employers provide a one-day paid Thanksgiving holiday?Hint: Use the normal approximation for the binomial distribution. Do not round the variance, round the standard deviation to 3 decimal places. e.g. if your standard deviation is 8.297441099, use 8.297. Leave you z-values to 2 decimal places, if your z value is 1.3094, use 1.31 as your z value.
