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.
One question asked was as follows: The term affirmative action has different meanings to different people. Please tell me which statement best describes what you mean by the term: First, affirmative action means granting preferences to women and certain racial and ethnic groups. Second, affirmative action means promoting equal opport unities for all individuals without regard to their race, sex, or ethnicity.” The options “Neither or Both” were not given and were recorded only if the respondent offered them. The first statement was chosen by 37%, the second one by 43%, Neither” by 13%, and “Both” by 2%. The remainder said, ‘Don’t know.” The organization that comm issioned the poll, the California Association of Scholars, issued a press release that said in reference to this quest ion, These findings demolish the claim that the faculty at UC wants preferential policies.” Refer to the Possible Sources of Response Bias in Surveys” in Section 5.6, and discuss them in the context of this question and resulting press release.

- Let X be a random variable with support SX = {−3, 0.5, 3, −2.5, 3.5}. Part ofits probability mass function (PMF) is given bypX(−3) = 0.15, pX(−2.5) = 0.3, pX(3) = 0.2, pX(3.5) = 0.15.(a) Find pX(0.5).(b) Find the cumulative distribution function (CDF), FX(x), of X.1(c) Sketch the graph of FX(x).arrow_forwardA well-known company predominantly makes flat pack furniture for students. Variability with the automated machinery means the wood components are cut with a standard deviation in length of 0.45 mm. After they are cut the components are measured. If their length is more than 1.2 mm from the required length, the components are rejected. a) Calculate the percentage of components that get rejected. b) In a manufacturing run of 1000 units, how many are expected to be rejected? c) The company wishes to install more accurate equipment in order to reduce the rejection rate by one-half, using the same ±1.2mm rejection criterion. Calculate the maximum acceptable standard deviation of the new process.arrow_forward5. Let X and Y be independent random variables and let the superscripts denote symmetrization (recall Sect. 3.6).
