As a student project Natalie would like to see whether there is statistical evidence Earth is warmer today versus 30 years ago. She randomly samples 100 locations around the world and collects the annual average high for each location for the years 1985 and 2015. She proceeds to compare the differences among the time periods with respect to location. What procedure should be used to test whether the average difference in temperature between the locations is greater than zero
