A gardener measures the temperature (°C) in his greenhouse in two-hour intervals between 10:00 and 20:00 one day. The results are shown in the table below:

a. Plot a line graph of the data. 

b. The gardener looks at the results and thinks that one of them must be wrong. Circle the result that is likely to be incorrect on your graph. Justify your answer. 

c. On your graph mark a new position for the point you circled in part (b) and justify your answer. 

d. Estimate the likely temperature of the greenhouse at 13:00.
