STAT_10D_Practice Score: 6.31/8 4/5 answered Question 1 Let's put together everything you've learned about confidence intervals for proportions, with a focus on confidence intervals for the difference in proportions between two groups. Are Instagram users more liberal than those who don't use the platform? The goal of this assignment is to use confidence intervals to determine if there is a difference in the proportions of people who have liberal political views based on whether or not they use Instagram, a social media platform. The data are from the 2016 General Social Survey (GSS). The GSS is a survey conducted every two years to gather information about behaviors and attitudes on a variety of issues for adults (18+ years old) in the United States. Survey respondents are from a list of randomly selected households. The GSS contains over 900 variables. The data for this analysis are from the gss16' dataset in the dsbox R package. The variables of interest are . instagram: Yes if the respondent said they use Instagram; no if not; NA removed . is_liberal: Yes if the respondent identified their political views as "Slightly liberal," "Liberal," or "Extremely liberal;" no otherwise The first 15 observations for the GSS dataset are provided in the table below. instagram is_liberal No Yes No No No No No No No Yes No Yes No No No Yes No Yes No No No NoThe first 15 observations for the GSS dataset are provided in the table below. instagram is_liberal No Yes No No No No No No No Yes No Yes No No No Yes No Yes No No No No No Yes No No No No No No Data from the 2016 General Social Survey (GSS).
