Question to investigate:For the population of Race IAT participants, is birth-gender related tothe participants' reported preference black people?1. Which question are you investigating? Copy and paste the question into yourresponse.2. What is the explanatory variable, and what is the response variable?3. State your hypotheses in context (the variables should be clear in eachhypothesis).5. Interpret the expected counts for each response in the 3rd column of yourtable. No need to show how the expected counts were calculated, but eachinterpretation should include a relevant percentage.6. Determine whether conditions are met to use the chi-square test ofindependence. For each condition explain why the condition is met or notmet.7. Chi-square test of independence:o If conditions are met, use the StatCrunch chi-square output(included with your contingency table above) to state yourconclusion in context.o If conditions are not met, select a different question whereconditions are met. Repeat all steps above, but do not delete youroriginal work. Instead, include your new responses under yourprevious responses.o If conditions are not met for every question listed above with yourIAT data set, contact me.

A survey was conducted to determine whether hours of sleep per night are independent of age. A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age 40 or older. Sample data follow.

This question refers to a survey of a university's faculty members on affirmative action policies for the university. The survey was based on telephone interviews with a random sample of 1,001 faculty members conducted in December 1995. One of the questions asked was, "Do you favor or oppose using race, religion, sex, color, ethnicity, or national origin as a criterion for admission to the university?" Of the 704 male respondents, 45% said "Favor," and of the 297 female respondents, 72% said "Favor." (a) Find the conservative margin of error (in %) for the male respondents. (Round your answer to one decimal place.) % Use the conservative margin of error to compute an approximate 95% confidence interval for the percent who favored this policy at the time of the poll in the population of male faculty members. (Round your answers to one decimal place.) (_,_)% , % (b) Find the conservative margin of error (in %) for the females. (Round your answer to one decimal…
Statistical discrimination is: a preconceived bias, not based on reason or experience, against a group. O the use of observations about the average characteristics of a group to make inferences about an individual member of the group. a feeling of inferiority arising from membership in a small group. O judgments shaped by the unconscious attribution of particular qualities to specific groups.
Determine if the survey question is biased. If the question is biased, suggest a better wording. How often do you eat vegetables during an average month? Is the question biased? OA. Yes, because it does not lead the respondent to any particular answer. A better question would be "Why is eating vegetables good for you?" OB. Yes, because it influences the respondent into thinking that eating vegetables is good for you. A better question would be "Do you think that eating vegetables is good for you?" OC. No, because it influences the respondent into thinking that eating vegetables is good for you. OD. No, because it does not lead the respondent to any particular answer.
