Answer 1
(a) Figure 1 presents the trend of export volume to eight different countries from Australia
with a comparative display between 2004-05 and 2014-15 (Mario, 2014).
Figure 1: Export figures in Australian dollar (Millions) in 2004-05 and 2014-15
Careful inspection discloses that export to China and Japan has increased significantly
in capacity. Export to United Kingdom has decreased slightly. Exports to rest of the
countries have also increased in 2014-15 (Fisher, Drucker, and König, 2012, pp.55-
62).
(b) Figure 2 presents the trend of increase/ decrease in export percentage to the eight
different countries from Australia with a comparative display between 2004-05 and
2014-15 (Jelen, 2010).

Figure 2: Percentage change in Export figures between 2004-05 and 2014-15
Apparently conflicting to Figure 1, percentage change in export from Australia to the
eight countries indicates a negative change in export percentage corresponding to the
overall export figure. In 2014-15, export to China has grown so rapidly that it has
negatively affected export growth to other countries.
(c) From part (a) and part (b), the actual trend in change of Australian export is
detectable. Due to increase in total export volume, increase in export amount is
evident in Figure 1, except the fact that export to the United Kingdom (UK) has
decreased in amount. From Figure 2, the percentage change in export is clearly
visible. Part (b) signifies that export figure might have increased for seven countries
(except UK), but the increase in export volumes have not increased proportionally.
Unusually export to China has increased in percentage from 15.4% (2004-05) to
40.4% (2014-15) of overall export figures. This unusual increase in export to China
has eventually reduced the proportional growth in export to other countries. Therefore,
the trend in Figure 1 and Figure 2 looks to be contradictory in nature, although, the
real scenario is clear when both figures are analysed together (Pesaran, and Pesaran,
2009).

Answer 2
a. A frequency distribution with specified class limits (provided in the problem) has been
constructed. Table 1 presents the frequency distribution with classes and lower as well
as upper class limits.
Table 1: Frequency table for umbrella sold in 40 days
Class Lower Limit Upper Limit
Frequenc

30-40 30 40 2
40-50 40 50 4
50-60 50 60 8
60-70 60 70 11
70-80 70 80 8
80-90 80 90 5
90-
100 90 100 2
Inspection of the above table indicates that on most number of days (N = 11), umbrella
sales was between 60 and 70. Subsequently there were 8 days on which 70 to 80
umbrellas were sold (Remenyi, Onofrei, and English, 2011, pp.13-35).
