A data set contains Facebook Penetration and Internet penetration of 32 counties in 2012. We will use a regression model where y=percentage of Facebook users, :3: percentage of Internet users and conduct a hypothesis test for Ho : )3 = 0 against Ha : [3 7': 0. (The complete data set is available at https://istats. shinyapps.io/LinearRegression/ - Under Choose data set, click \"Internet 8: Facebook\") a) There are three assumptions : Linearity, Normality, Constant variance. Use plots in the next page to determine whether each assumption is met or not. Specify which plot you are using for each assumption. Check Canvas Study guide/summary table module and look for \"Regression assumptions\" document if you are not sure which plot to use. b) State the null and alternative hypothesis (again). c) Use a = 0.05. Based on the R output below, report the value of test statistic and pvalue. Draw a conclusion and interpret in context of the problem. d) It is known that 95% CI for 5 is b:|:(to'025,df=3o)(SE) = 0.4389:|:(2.04) (0.1030) = (0.228, 0.649). Interpret the result in context. > summ (1m (Facebook . Penetrat ion\" Internet . Penetrat ion) ) arr Coefficients: Estimate Std.
