Sarah lives beside the ocean in Eureka, California. Her penpal, Ruby, lives in Redding, California, which is located inland. As a school project one year, Sarah and Ruby decide to collect local climate data and compare the average monthly high and low temperatures from their cities. The data they collect are shown below. Month Eureka Average High Eureka Average Low Redding Average High Redding Average Low January 54°F 41°F 55°F 35°F February 55°F 43°F 58°F 38°F March 55°F 43°F 70°F 41°F April 56°F 45°F 71°F 45°F May 58°F 48°F 80°F 52°F June 60°F 51°F 89°F 60°F July 61°F 52°F 98°F 64°F August 62°F 53°F 97°F 61°F September 63°F 51°F 89°F 56°F October 61°F 49°F 69°F 45°F November 58°F 45°F 60°F 40°F December 55°F 42°F 55°F 34°F Based on the climate data that Sarah and Ruby collect, they can conclude that

Temperature variance at Redding > > Temperature variance beside at Eureka

Monthly temperatures at Redding are generally higher than the monthly temperatures beside the ocean at Eureka

Based on the climate data that Sarah and Ruby collect, they can conclude that

From the data we have

From the data it is observed that the temperatures beside the ocean in Eureka are lesser than and more stable (vary less) than the temperatures in Redding, also the temperatures in Redding are much higher than the temperatures beside the ocean in Eureka.
