Chapter 12.4, Problem 53E
Consider the following four intervals based on the data of Exercise 12.17 (Section 12.2):
- a. A 95% CI for
mean porosity when unit weight is 110 - b. A 95% PI for porosity when unit weight is 110
- c. A 95% CI for mean porosity when unit weight is 115
- d. A 95% PI for porosity when unit weight is 115
Without computing any of these intervals, what can be said about their widths relative to one another?

One operation of a mill is to cut pieces of steel into parts that will later be used as the frame for front seats in an automobile. The steel is cut with a diamond saw and requires the resulting parts to be
within 10.005 inch of the length specified by the automobile company. Data are collected from a sample of 50 steel parts and are shown in the following table. The measurement reported is the
difference in inches between the actual length of the steel part, as measured by a laser measurement device, and the specified length of the steel part. For example, the first value, -0.003,
represents a steel part that is 0.003 inch shorter than the specified length. Complete parts a through c

*9.1 A level with a collimation error of 0.00008 ft/ft is used in leveling a line
that has a sum of 525 ft for the backsight distances and only 1632 ft
for the foresight distances. If the observed elevation difference is
-6.07 ft, what is the elevation difference corrected for the collimation
error?
