Question

A dealer in recycled paper places empty trailers at various sites. The trailers are gradually filled by individuals who bring in old newspapers and magazines, and are picked up on several schedules. One such schedule involves pickup every second week. This schedule is desirable if the average amount of recycled paper is more than 1,600 cubic feet per 2-week period. The dealer’s records for eighteen 2-week periods show the following volumes (in cubic feet) at a particular site:

1,660
1,570
1,820
1,700
1,590
1,900
1,440
1,800
1,730
1,770
1,680
2,010
1,750
1,580
1,720
1,620
1,900
1,690

Is there enough evidence to suggest that two-week pick-up schedule is desirable? Use 5% significance level. Clearly state the 6 steps of the hypothesis test you do and show all your work.

NOTE: Since you have the data make sure to check if the the conditions for the above test are satisfied.
