Consider a project with a mean time of completion of 14.67 days; the variance of the time of completion is 2.83 days. What is the probability of finishing the project in 17 days? Response Feedback: Find P(T < 17) where T is Normally distributed with a mean of 14.67 and a standard deviation of 1.68 (recall that standard deviation is the square root of the variance). This would be the same as P(Z < 1.39) where Z has a standard Normal distribution. This can be looked up from the standard Normal distribution tables.
