5.42 A dealer in recycled paper places empty trailers at various sites. The trailers are gradu- ally 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 desir- able if the average amount of recycled paper is more than 1,600 cubic feet per 2-week period. The dealer's records for 18 2-week periods show the following volumes (in cubic feet) at a particular site: 1,60 1,820 1,590 1,440 1,730 1,680 1,750 1,720 1,900 1,570 1,700 1,900 1,800 1,770 2,010 1,580 1,620 1,690 y = 1,718.3 and s= 137,8 a. Assuming the 18 2-week periods are fairly typical of the volumes throughout the year, is there significant evidence that the average volume u is greater than 1,600 cubic feet? b. Place a 95% confidence interval on a. c. Compute the p-value for the test statistic. Is there strong evidence that u is greater than 1,600?

![5.42 A dealer in recycled paper places empty trailers at various sites. The trailers are gradu-
ally 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 desir-
able if the average amount of recycled paper is more than 1,600 cubic feet per 2-week period.
The dealer's records for 18 2-week periods show the following volumes (in cubic feet) at a
particular site:
1,660 1,820 1.590
1,440
1,730
1,680
1,750 1,720 1.900
1,570 1,700 1,900 1,800 1,770 2,010 1,580 1,620 1,690
y = 1,718.3 and s = 137.8
a. Assuming the 18 2-week periods are fairly typical of the volumes throughout the
year, is there significant evidence that the average volume u is greater than 1,600
cubic feet?
b. Place a 95% confidence interval on u.
c. Compute the p-value for the test statistic. Is there strong evidence that u is
greater than 1,600?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc5c7d491-b8f4-4a3a-8fb7-26cd06deda1d%2F7c10c198-68fb-4bf9-b51b-190d190cc10b%2F6imwc04_processed.jpeg&w=3840&q=75)
