A garbage collection division of a local council is interested
in their garbage statistics. They contract you as a data analyst to
analyse their collection processes. The first task is to assess the
performance of two collection teams to determine which team is
faster at completing their collection runs. The council records the
time it takes for two of their teams to complete the collection
runs for each suburb and records these in a data base. A random
sample of the data base is shown below with the collection times
for the respective suburb.
Report the 95% confidence interval for the difference in average
collection times between the two teams. Write a sentence
interpreting this interval in plain language. Does this confidence
interval support the decision made in part (c)?
