b) From part a) it can be noticed that China had the highest export, followed by
Japan. It can be noticed that from 2004-2005 and 2014-2015 that China had
increased its export. The same applied to Japan, United States, India, and
Singapore. The exports for New Zealand and the United Kingdom decreased.

exports in 2014-15 while Japan had the highest percentage of exports in
2004-05. The same increase applied to China’s exports in the same years
unlike the remaining seven countries which has been reduced the exports.
Question 2

a) The graph below shows the relative frequency and frequency graph
Fig 2.1: Histogram

It can be noticed that the umbrella sales had the highest frequency between 60 -70.
This means that for the 40 days, the highest number of the umbrellas that were sold
were between 60-70 umbrellas.
