SSon 3 3.28 Global Warming. The following data (taken from the article-2.5 Effects of climate change on global food production under SRES emissions and socio-economic scenarios", published in Global En vironmental Change, Vol. 14, 2004, pp. 53-67), shows the potential changes (%) in national cereal yields for a few countries with carbon dioxide effects. aho Change in yield (%) 2020 Country 2080 b) -16 6 2.5 0 10 -10 2.5 -2.5 USA 10 0 China South Africa 0 Australia India 2.5 -2.5 a. Find the mean and median of the percentage of change in 2020, b. Find the mean and median of the percentage of change in 2080 mean O. 7 e. If you had a list of only one country to demonstrate the percentage change in year, which would be the modal country for 2020 and 2080? 2 d. What might explain the difference in the modal country for 2020 and 2080? 3.77 The Beatles. The English rock band. The Beall in Liverpool in 1960.

Answer (C)
It is based on some general information
we know that the global warming is affecting the cereal yield negatively every year, i.e. the cereal production is decreasing every year due to the global warming.
so, for all countries we can see that the south africa is showing negative change from 0% in 2020 to -10% in 2080.
USA is showing 2.5%(positive) change in yield from 2020 to 2080
Canada is showing 0%(no change) change in yield from 2020 to 2080
china is showing 10%(positive) change in yield from 2020 to 2080
South africa is showing -10%(negative) change in yield from 2020 to 2080
Australia is showing 2.5%(positive) change in yield from 2020 to 2080
India is showing -2.5%(negative) change in yield from 2020 to 2080
So, south africe is showing highest negative change in % yield
Thus, we can consider South Africe as the modal country for 2020 and 2080.
