C8. The GSS 2014 included a series of questions about what it takes to be a good citizen. Respondents were asked, to be a good citizen, how important was it "to help people in America who are worse off than yourself" (HELPUSA) and “to help people in the rest of the world who are worse off than yourself" (HELPWRLD). Answers were measured on a 7-point scale: 1 for each with respondent's political party (RPartyId) as the independent variable. Set alpha at .05 to assess the significance of each model. = not important at all to 7 = very important. We ran ANOVA models Descriptives 95% Confidence Interval for Std.

Researchers were interested in how much time balance (i.e., the degree to which you have enough time to do what you like) is related to happiness. They asked 12 adults to answer two questions (on 1 – 8 scales): (a) in a typical week, how much of your time are you able to spend doing the kinds of things that you enjoy (with higher scores indicating more time balance) and (b) taking all things together, how happy would you say you are (with higher scores indicating more happiness)? The research hypothesis is that there is an association between time balance and happiness. Use the Table of Descriptive statistics, correlation (r), the standard error of the correlation (SEr), and the r to zr Table, to go through the steps to compute the 95% CI. Report all values (excluding critical values) to TWO decimal places.Report critical values to THREE decimal places.

A substance abuse counselor wants to demonstrate the effect of situational stress on alcohol cravings. He recruits two groups of men who are similar in respect to history of alcohol use and demographic variables. He divides them in to two groups. In one group(n=11), the men are exposed to a stressful situation and then asked to complete a measure rating their alcohol cravings on a scale from 0-10, where 0 representsno cravings and 10 represents intense cravings. In the second group (n=10), the men are exposed to a neutral situation and asked to complete the same measure. What test  and graph should I create to find out if a stressful situation result in more intense alcohol cravings than a non-stressful situation?

In a study assessing helping behavior among college students on their way to class, you recruit 10 students. You tell some participants that they are late for class and need to rush. You tell others they are right on time. Finally, you tell others they have lots of time before class. As they walk across campus, they come across a man (actually a confederate) who appears to need help. You measure the extent to which the participant noticed that the confederate needed help (1 = did not notice to 9 = really noticed). Which hypothesis test would you calculate? F test Independent sample t-test z test Dependent sample t-test
