I. A recycled paper distributor places empty containers in various locations; those gradually fill up 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 amount of recycled paper media 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? Write down all the parts of the hypothesis testing procedure.

II. Suppose that, from previous elections in a state, for a candidate for governor to be elected, he must win at least 80 percent of the votes in the northern section of the state. The incumbent governor is interested in evaluating his chances of returning to office and plans to conduct a survey of 2,000 registered voters in the northern section of the state. Apply the procedure to test hypotheses and evaluate the governor's chances of being reelected, with a significance level of 0.05, if the poll revealed that 1,550 of the 2,000 possible voters in the northern part of the state planned to vote for the current governor. . Are the sample results close enough to expected to conclude that the difference is due to sampling error? Write down all the parts of the hypothesis testing procedure.

ps: i need to know the process how to do it and the answer of the two questions
