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? If the scatter plot looks linear then, yes, the line can be used for prediction, because r is less than the negative critical value. " If the scatter plot looks linear then, no, the line cannot be used for prediction, because r is less than the negative critical value. 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? 1=0 and the sample size, n=100. The df=n-2=99. The critical value does not matter so ris significant. 1=0 and the sample size, n, is 100. The df=n-2=99. The critical values show that / is significant. 1=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- QUESTION 10 If there are 106 data points in a set of data, what is the number of degree of freedom
