randomly sampled did not randomly assign di not randomly sample randomly assigned 0 O O O Can eating nuts during pregnancy help children avoid nut allergies? Researchers studied over 8000 children who were born in the early 19905 to mothers who were part of the Nurses' Health Study ll. Children whose mothers ate the most nuts during pregnancy (at least 5 times per week) were signicantly less likely to develop nut allergies than children whose mothers ate the least amount of nuts during pregnancy (less than once per month). What is the largest population to which we can generalize these results? O All mothers who eat nuts during pregnancy. 0 All mothers like the ones in the study. 0 Children with nut allergies. O All mothers. l: Question 1 3.33 pts In a classic study, researchers investigated the tendency of sports fans to \"bask in reected glory\" by associating themselves with winning teams. In the study, researchers called randomly selected students at a major university with a highly ranked football team. Half the students were randomly assigned to answer questions about a recent game the team lost, and the other half were asked about a recent game the team won. If the students were able to correctly identify the winner (showing they were fans of the team), they were asked to describe the game. Researchers recorded if the students identied themselves with the team by their use of the word we in the description (\"We won the game\" versus \"They won the game\"). Following a win, 32% of the students identified with the team by using "we" compared to only 18% after a loss. This difference is statistically significant. Based on the study, is it reasonable to say that winning a game causes a stronger identification with the team? Explain your answer. [ Select ] V The researchers [ Select ] V the students to describe a football game after a win or loss.In cooperation with researchers from Cornell University, Facebook randomly selected almost 700,000 users for an experiment in \"emotional contagion.\" Users' news feeds were manipulated (without their knowledge) to selectively show postings from their friends that were either more positive or more negative in tone, and the emotional tone of their own subsequent postings was measured. The researchers found evidence that people who read emotionally negative postings were more likely to post messages with a negative tone and those reading positive messages were more likely to post messages with a positive tone. The research was widely criticized for being unethical. Explain why. Select all that apply. C] The Facebook users involved in the study did not know that they were going to be subjected to treatments. C] The Facebook users were not randomly assigned to treatment groups. C] This was not a double-blind experiment. C] The Facebook users did not provide informed consent before the study was conducted
