Find the correlation coefficient and report it accurate to three decimal places.
r=0.974
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 = 94.9
Based on the data, calculate the regression line (each value to three decimal places)
y =0.848
X+2.870
Predict what value (on average) for the response variable will be obtained from a value of 57.6 as the
explanatory variable. Use a significance level of a 0.05 to assess the strength of the linear correlation.
