Chapter 5, Problem 5.111E
Exercises 5.110 to 5.112 refer to a survey of University of California faculty members on affirmative action policies for the university (Roper Center, 1996). The survey was based on telephone interviews with a random sample of 1001 faculty members conducted In December 1995.
Refer to Exercise 5.110. Of the 166 arts and humanities faculty members, 66% favored the policy, while of the 229 engineering, mathematical, and physical sciences facuhy, 38% favored it.
a. Find the conservative margin of error for the arts and humanities faculty, and use it to compute an approxim ate 95% confidence interval for the percent of them in the population who favored this policy.
b. Repeat the analysis in part (a) for the engineering and sciences faculty.
c. Compare the approximate 95% confidence intervals you found in parts (a) and (b), and comment on whether you think faculty members in these disciplines in the populat ion dif1tnd on thk question at the time of the poll.

BUSINESS DISCUSS
A researcher wishes to estimate, with 90% confidence, the population proportion of adults who support labeling
legislation for genetically modified organisms (GMOs). Her estimate must be accurate within 4% of the true proportion.
(a) No preliminary estimate is available. Find the minimum sample size needed.
(b) Find the minimum sample size needed, using a prior study that found that 65% of the respondents said they support
labeling legislation for GMOs.
(c) Compare the results from parts (a) and (b).
...
(a) What is the minimum sample size needed assuming that no prior information is available?
n =
(Round up to the nearest whole number as needed.)
