You obtain the regression equation y = -2.585x - 16.627 with a correlation coefficient of r = -0.475 (which is significant at ? = 0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 180 on the response variable. What is the predicted explanatory value? x = (Report answer accurate to one decimal place.)

Run a regression analysis on the following bivariate set of data with y as the response variable. Find the correlation coefficient and report it accurate to three decimal places. r = 0.924. 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.) r^2 = 90%. Based on the data, calculate the regression line (each value to three decimal places). y = x +. Predict what value (on average) for the response variable will be obtained from a value of 61 as the explanatory variable. Use a significance level of alpha = 0.05 to assess the strength of the linear correlation. What is the predicted response value? (Report answer accurate to one decimal place.)
