1. The problem involves analyzing the cost of electricity per kWh over the years 1994 to 2009, as well as interpreting data about minutes to run 5km, and some statistical measures like mean and range. 2. For the cost of electricity, the data points show a mostly flat trend near £9 from 1994 to 1998, a dip to about £8.2 in 1999–2000, a rise back to about £9.3 from 2001–2004, a jump to about £11.3 in 2005–2006, and further increases to about £12.3 in 2007 and about £13 in 2008. 3. The minutes to run 5km data ranges from 19.7 to 44.2 minutes, with a mean of 32 and a range of 24.5. The range is calculated as the difference between the maximum and minimum values. 4. The table with values 7.5 1; 8 6; 9 2; 10 2 likely represents frequency data for some variable. 5. Since no explicit question is asked, the key takeaway is understanding how to interpret line graphs, calculate mean and range, and read frequency tables. 6. For example, the mean is calculated as $$\text{mean} = \frac{\sum \text{values}}{\text{number of values}} = 32$$ and the range as $$\text{range} = \text{max} - \text{min} = 44.2 - 19.7 = 24.5$$. 7. This problem is primarily about data interpretation and basic statistics.
