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.)
%
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 14 as the
explanatory variable.
What is the predicted response value? (Report answer accurate to one decimal place.)
