Please help. I'm not sure what to do after calculating the Z score.

1. Among coffee drinkers, men drink a mean of 3.8 cups per day with a standard deviation of 0.7 cups. Assume the number of cups per day follows a normal distribution. (use appendix tables 1 & 1a) (round answers to 4 decimal places) = 3.8 and? = 0.7
   1. What proportion of men drinks 2 cups per day or more?
