Statistics: The mean height of adult males is 72 inches, with a standard deviation of 2.5 inches. Consider the heights to follow a normal distribution. A. If a man is 71 inches tall, in what percentile does he lie?

B. What percentage of men will be between 71 and 75 inches tall?

C. How tall must a man be to be in the 98th percentile?

Some help would be sincerely appreciated, this is my 3rd all nighter in a row, posting again because I got no real answers.
