The amount of time that people spent at Grover Hot Springs is normally distributed with a mean of 68 minutes and a standard deviation of 18 minutes. Suppose one person at the hot springs is randomly chosen. Let X= the amount of time that person spent at Grover Hot Springs. Round all answers to 4 decimal places where possible. I only need help on questions B, and C.
