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.

You suspect that people living in urban areas produce on average more garbage (X)than those living in rural areas (Y). To verify this opinion, you draw two samples and collect information on the amount of garbage produced in a month (measured in kilos). The first sample, made of 8 subjects living in an urban area, provides a sample mean equal to 40.5 and a sample standard deviation equal to 5.6; in the second sample, made of 10 subjects living in rural areas, the sample mean is 35.6 and the sample standard deviation is 7.5. It is assumed that the two populations are normal with the same unknown variance.Test the null hypothesis that the two population means are equal against a one-sided alternative according to which people living in urban areas produce on average more garbage than those living in rural areas. Use a 1% significance level.
