Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your finding to state whether or not the given r represents a significant linear correlation. Use a significance level of 0.01.  r=0.767 and n=25 Use the table below for this problem.Table for r(1).png  1. Critical value = 2. Significant linear correlation exist? YES or NO 3. Explain the reason for your decision at 2.

Which of the following statements concerning the linear correlation coefficient, r are true? I: If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables. II: If the slope of the regression line is negative, then the linear correlation coefficient is negative. III: The value of the linear correlation coefficient always lies between  -1 and 1 . IV: A linear correlation coefficient of 0.62 suggests a stronger linear relationship than a linear correlation coefficient of -0.82.
