- A sample of 20 pairs of bivariate data has a linear correlation coefficient of r=0.65. Determine if a linear equation exists or not. Use a 1% level of significance. Find the Decision points for levels 1% and 5 %
choices are +/- .537 +/.444 +/- .423 +/- .561 - A sample of 28 pairs of bivariate data has a linear correlation coefficient of r=-0.27 at a .02 level of significance, use a t test to determine if linear correlation exists or not. Give the hypothesis, find the critical values, Give the test statistic what is your conclusion
- Would you usually find an equation of a regression line if a linear correlation does not exist?
