Suppose that we are interested in how much money the average football fan spends on food at a single football game. To try to answer this, we asked 72 randomly selected football fans at a game how much money they had spent on food. The sampled results show that the sample mean and standard deviation were NZ$36.00 and NZ$14.65, respectively. Use the sample statistics to calculate an estimate of the standard error for the sample mean. Give your answer to 2 decimal places.
