The number of lightning strikes on a square kilometer of open ground in a year has a mean of 6 and a standard deviation of 2.4. Counts of strikes on separate areas are independent. The Ntional Lightning Detection Newtowk uses automatic sensors to watch for lightning in areas of 10 square kilometers.
What are the mean and standard deviation of the total number of lightning strikes observed?
What are the mean and standard deviation of the mean number of strikes per square kilometer?
