Chapter 7.2, Problem 19E
The article “Limited Yield Estimation for Visual Defect Sources” (IEEE Trans. on Semiconductor Manuf., 1997: 17–23) reported that, in a study of a particular wafer inspection process, 356 dies were examined by an inspection probe and 201 of these passed the probe. Assuming a stable process, calculate a 95% (two-sided) confidence interval for the proportion of all dies that pass the probe.

The report "Comparative Study of Two Computer Mouse Designs"t included the following description of the subjects used in an experiment.
Twenty-four Cornell University students and staff (12 males and 12 females) volunteered to participate in the study. Three groups of 4 men and 4 women were selected by their stature to represent the
5th percentile (female 152.1 ± 0.3 cm, male 164.1 ± 0.4 cm), 50th percentile (female 162.4 ± 0.1 cm, male 174.1 ± 0.7 cm), and 95th percentile (female 171.9 ± 0.2 cm, male 185.7 ± 0.6 cm) ranges.... All
subjects reported using their right hand to operate a computer mouse.
This experimental design incorporated direct control and blocking.

The article "Withdrawal Strength of Threaded Nails" (D. Rammer, S. Winistorfer, and D.
Bender, Journal of Structural Engineering, 2001:442–449) describes an experiment
comparing the withdrawal strengths for several types of nails. The data presented in the
following table are consistent with means and standard deviations reported in the article for
three types of nails: annularly threaded, helically threaded, and smooth shank. All nails had
diameters within 0.1 mm of each other, and all were driven into the same type of lumber.

- The authors of the paper “Ultrasound techniques applied to body fat mea-surement in male and female athletes” (Journal of Athletic Training [2009]: 142–147) compared two different methods for measuring body fat percentage. One method usesultrasound and the other method uses X-ray technology. The accompanying table givesbody fat percentages for 16 athletes using each of these methods (a subset of the datagiven in a graph that appeared in the paper). For purposes of this exercise, you can assume that the 16 athletes who participated in this study are representative of the pop-ulation of athletes. Do these data provide convincing evidence that the mean body fat percentage measurement differs for the two methods?

Suppose that for aluminum alloy sheets of a particular type, its mean value and standard deviation are 70 GPa and 1.6 GPa, respectively (values given in the article "Influence of Material Properties Variability on Springback and Thinning in Sheet Stamping Processes: A Stochastic Analysis" (Intl. J. of Advanced Manuf. Tech., 2010: 117-134)).
