Answer:

Step-by-step explanation:

Statistically this is valid

But, in Alaska average daytime summer temperatures range from approximately 55 to 78 °F (12.8 to 25.6 °C); average daytime winter temperatures are about 5 to 30 °F (−15.0 to −1.1 °C). SO, they don't need cooling when compared to rest of the USA. Therefore this will not be valid.
