In an experiment to determine the half-life of a radioactive sample, activity A and time t are recorded over a 10 hour period according to A = A_0 * e^(-lambda * t).

Add suitable data to the third column of Table 3, plot a straight line graph on the grid provided on page 11, and state the equation of the line plotted.

This question uses a figure or table from the paper — you'll see it when you practise.
