1) Average annual temperatures for year 2011 are more than average annual temperatures for years 2013.
2) Average annual temperatures for year 2010 are more than average annual temperatures for years 2012.

Solution

Statement 1):

Average annual temperature in year 2011 = (12 + 30 + 22 + 30)/4 = 23.5

Average annual temperature in year 2013 = (16 + 32 + 24 + 32)/4 = 26

Average annual temperature in year 2011 > Average annual temperature in year 2013

Statement 1) is False.

Statement 2):

Average annual temperature in year 2010 = (14 + 32 + 24 + 28)/4 = 24.5

Average annual temperature in year 2012 = (16 + 34 + 24 + 30)/4 = 26

Average annual temperature in year 2010 < Average annual temperature in year 2012

Statement 2) is false.
