A 2014 Pew Research Center Survey asked 2,002 adults about the intersection of politics and science. Of the survey participants, 1,281 responded "neither" when asked if they perceive scientists as politically liberal or conservative. What are the values of p′, "successes", or the estimated proportion of Americans who perceive scientists as neither politically liberal or conservative, and q′, the estimated proportion of Americans who perceive scientists as politically liberal or conservative? Answer in decimal form, rounding to the nearest hundredth.
ReAb. a question can influence eyewitness memory. In the study, college students watched a film of ap automobile accident and then were asked questions about what they saw. One group was asked, "About how fast were the cars going when they smashed into each other?" Another group was asked the same question except the verb was changed to "hit" in- stead of "smashed into." The "smashed into" group reported significantly higher estimates of speed than the "hit" group. Suppose a researcher repeats this study with a sample of today's college students and obtains the following results. Estimated Speed Smashed into Hit n 15 n = 15 M = 40.8 M = 34.0 SS = 510 SS = 414 a. Do the results indicate a significantly higher esti- mated speed for the "smashed into" group?
