A golfer keeps track of his score for playing nine holes of golf (half a normal golf round). His mean score is 78 with a standard deviation of 9. Assuming that the second 9 has the same mean and standard deviation, what are the mean and standard deviation of his total score if he plays a full 18 holes? The mean of his total score is . (Round to the nearest integer as needed.)

A golfer keeps track of his score for playing nine holes of golf (half a normal golf round). His mean score is 85 with a standard deviation of 11 . Assuming that the second 9 has the same mean and standard deviation, what is the mean and standard deviation of his total score if he plays a full 18 holes?
The average score of all golfers for a particular course has a mean of 81 and a standard deviation of 4.8. Suppose 89 golfers played the course today. Find the probability that the average score of the 89 golfers exceeded 82. The probability that the average score of the 89 golfers exceeded 82 is ______
