e. What is the probability that the project will take 30 or MORE days to complete? Use the expected project completion time you entered in part c above (rounded to 2 decimal places), and then round your z value to 2 decimal places (e.g., 1.38). Use Excel's NORM.S.DIST() function to find the correct probability for your computed z-value, and round that to 4 decimal places (e.g., .8127). Round your final answer to 4 decimal places and enter the probability as a decimal (e.g., .1873).
