Using SPSS, analyze the relationship between respondents’ marital status (MARITAL) and whether they believe it is alright for a couple to live together without intending to get married (COHABOK) using crosstabulation. Which marital status category is most disapproving of nonmarital cohabitation? Which marital status category is most approving of nonmarital cohabitation? Is the relationship between marital status and attitude toward nonmarital cohabitation statistically significant at the .05 level? Compute and interpret an appropriate measure of association for this relationship.

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.

"Fruit Juice May Be Fueling Pudgy Preschoolers, Study Says" is the title of an article that appeared in the San Luis Obispo Tribune. This article describes a study that found that for 3- and 4-year-olds, drinking something sweet once or twice a day doubled the risk of being seriously overweight one year later. The authors of the study state the following. Total energy may be a confounder if consumption of sweet drinks is a marker for other dietary factors associated with overweight.t Give an example of a dietary factor that might be one of the potentially confounding variables the study authors are worried about. O Children who drink sweet drinks have stricter parents who let them eat and drink whatever they want. Children who drink sweet drinks have more lenient parents who track their weight and focus on their health more. O Children who drink sweet drinks may also drink less each day than other kids. Children who drink sweet drinks may also eat a lot of sweet foods and high-calorie…
