For a given line of best fit, you computed that r = - 0.7204 using n = 8 data points and the critical value is 0.707. Can the line be used for prediction? Why or why not? O If the scatter plot looks linear then, yes, the line can be used for prediction, because r is less than the negative critical value. O If the scatter plot looks linear then, no, the line cannot be used for prediction, because r is less than the negative critical value. O If the scatter plot looks linear then, yes, the line can be used for prediction, because r is greater than the negative critical value. O If the scatter plot looks linear then, no, the line can be used for prediction, because r is greater than the negative critical value. QUESTION 9 For a given line of best fit, you compute that r = 0 using n = 100 data points. Can the line be used for prediction? Why or why not? O 1=0 and the sample size, n=100. The df=n-2=99. The critical value does not matter so ris significant. Or=0 and the sample size, n, is 100. The df=n-2=99. The critical values show that ris significant. OF=0 and the sample size, n, is 100. No matter what the dis are,/=0 is always between the two critical values in the chart so ris not significant. O r=0 does not tell us anything
