Question: This exercise is also Exercise. A random sample of 1001 University of California faculty members taken in December 1995 was asked, "Do you favor or oppose using race, religion, sex, color, ethnicity, or national origin as a criterion for admission to the University of California?" (Roper Center, 1996). Fifty-two percent responded "favor."
a. What is the population for this survey?
b. What is the approximate margin of error for the survey?
c. Based on the results of the survey, could it be concluded that a majority (over 50%) of all University of California faculty members favored using these criteria at that time? Explain.
Exercise: Refer to Example, in which for a sample of 1003 American adults, .56 was the proportion who think that it is somewhat or very likely that intelligent life exists elsewhere. Compute a 99% confidence interval for the population proportion.
Example: Is There Intelligent Life on Other Planets? In a 2008 Scripps Howard News/ Ohio University survey of 1003 randomly selected Americans, 56% of the sample said that it is either very or somewhat likely that there is intelligent life on other planets (Source: www.scrippsnews.com/node/34758).
