The historical on-time percentage for Amtrak's Sunset Limited is 10 percent. In July, the train was on time 2 times in 28 runs. Hint: Use Excel to calculate the cumulative binomial probability P(X ≤ 2 | n = 28, ππ = 0.10). Assume α = 0.1. Find the probability. (Round your answer to 4 decimal places.)
