Question: Florida Power & Light (FP&L) Company has enjoyed a reputation for quickly fixing its electric system after storms. However, during the hurricane seasons of 2004

Florida Power & Light (FP&L) Company has enjoyed a reputation for quickly fixing its electric system after storms. However, during the hurricane seasons of 2004 and 2005, a new reality was that the company’s historical approach to emergency electric system repairs was no longer good enough (the Wall Street Journal, January 16, 2006). Data showing the days required to restore electric service after seven hurricanes during 2004 and 2005 follow.

Hurricane Days to Restore Service

Charley ............ 13

Frances ............ 12

Jeanne ........... 8

Dennis ........... 3

Katrina ............. 8

Rita ............ 2

Wilma ........... 18

Based on this sample of seven, compute the following descriptive statistics:

a. Mean, median, and mode

b. Range and standard deviation

c. Should Wilma be considered an outlier in terms of the days required to restore electric service?

d. The seven hurricanes resulted in 10 million service interruptions to customers. Do the statistics show that FP&L should consider updating its approach to emergency electric system repairs? Discuss.
