Web(b) On the basis of the value of the linear correlation coefficient, would you conclude, at the r > 0.9 level, that the data can be reasonably modeled by a linear equation? Explain. Yes, the correlation coefficient is very close to 0, which indicates a near perfect linear correlation. Yes, the correlation coefficient is very close to 1, which ... WebMath Statistics Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using α=0.05. Is there sufficient evidence to conclude that there is a linear correlation between court incomes and justice salaries?
