Run a regression analysis on the following hivariato cot of data with y as the response variable. 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.) r2= 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 74.5 as the explanatory variable. Use a significance level of =0.05 to assess the strength of the linear correlation. What is the predicted response value? (Report answer accurate to one decimal place.) y=
