Using the research scenario and data from Table2 below, conduct appropriate statistical analysis in Jamovi and answer questions 1-5. Research scenario: You hear a lot of talk about increasing global temperature, so you decide to see for yourself if there has been an actual change in recent years. You know that the average land temperature from 1951-1980 was 8.79 degrees Celsius. You find annual average temperature data from 1981-2017 (Table 1) and decide to look at whether there is a difference between the average temperature in the period between 1951-1980 and the average temperature in the period between 1981-2017. Table 2. Average land temperature from 1951-1980 in degrees Celsius.
