Run a regression analysis on the following bivariate set of data with y as the response variable. X y 24 28.3 19.3 1.8 34.8 20.6 9.9 9.6 41.7 15.2 15.9 -0.9 25.1 14.4 74.8 52.3 29.4 24.4 59.9 26.8 19.5 9.5 60 48.4 Find the correlation coefficient and report it accurate to three decimal places. r = What proportion of the variation in y can be explained by the variation in the values of x? Report answer as a percentage accurate to one decimal place. (If the answer is 0.84471, then it would be 84.5%...you would enter 84.5 without the percent symbol.) 196 Based on the data, calculate the regression line (each value to three decimal places) y = Predict what value (on average) for the response variable will be obtained from a value of 28.7 as the explanatory variable, Use a significance level of a = 0.05 to assess the strength of the linear correlation. What is the predicted response value? (Report answer accurate to one decimal place.) V =
