This is for my QMS202 stats class, could you please answer this question ASAP.

The City of Toronto is attempting to reduce the number of people in parks. Assume that the weight of the garbage bin is a good approximation for the number of people in the park. In the past, garbage weights averaged 12 kilograms during the month of April. Based on recent sample, the average weight of a garbage bin is 8 kilograms, however only half the number of garbage bins are available. The standard deviation of the sample is 1.2 kilograms.
