Lightning strikes

5.46    Lightning strikes. The number of lightning strikes on a square kilometer of open ground in a year has mean 6 and standard deviation 2.4. (These values are typical of much of the United States.) Counts of strikes on separate areas are independent. The National Lightning Detection Network uses automatic sensors to watch for lightning in an area of 10 square kilometers.

(a)   What are the mean and standard deviation of the total number of lightning strikes observed?

(b)   What are the mean and standard deviation of the mean number of strikes per square kilometer?
