c. The plot indicates that that in the period 2004-05, Japan was the leading export
market for goods and serviced (Keller, 2015). However, in the period 2014-15 China
was the leading export in the top eight export markets. In general, the plot suggests
that there was an increase in the quantity of export between the periods 2004-05 and
2014-15. New Zealand and the United Kingdom did not show a significant change in
their export value. The value of export from the United Kingdom slightly decreased
from A$ 9.2 billion to A$ 8.6 billion. This was th4 only country among the top eight
export market that had a decline in their export value.

The plot indicates that there was a general decline in the proportion of market share
among the top eight exports markets for goods and services. China had a tremendous
increase in its market share from 15.4% to about 40.4%. New Zealand and the United
Kingdom had the highest drop in market share from 11.8% to 5.5% and 8.9% to 3.8%
respectively. Thus, it can be concluded that although the market value of most of the
country increased, the market shared among the top eight export decreased (except for
China) (Silvey, 2017).
