Table 1 shows that there were 25 000 sentences handed down in the South West region in 2010. Table 2 shows that 0.4% of recorded offences were arson attacks, revealing that in the South West exactly 100 arson sentences were given for arson in that year. Which of the following assumptions, if any, are required for this argument? 1 The number of recorded arson attacks in the South West is proportionate to the total number of such attacks across all regions. 2 The number of recorded offences in each region is the same as the number of sentences in that region.
