I. A recycled paper distributor places empty containers in various locations; these are gradually filled with old newspapers and similar materials brought by various individuals. The containers are collected (and replaced with empty ones) following different routes. In one of these routes, the collection is done every two weeks. This plan is advisable if the average amount of recycled paper in each two-week period is greater than 1600 cubic feet. Different records for 18 two-week periods show the following volumes (in cubic feet) for a particular location:

1660 1820 1590 1440 1730 1680 1750 1720 1900

1570 1700 1900 1800 1770 2010 1580 1620 1690

Suppose these figures represent the results of a random sample. Do you support the alternative hypothesis, using = 0.10? Include all the parts of the hypothesis testing procedure.
