Which of the following are NOT true about the linear correlation coefficient? Select all that apply.
r measures the strength of all kinds of correlations, not just linear correlation
O If r=0.95, it means the slope of the best fit line is m=0.95
If r is close to zero, it means that there is little linear correlation between the x and y variables
If r=0.95, it means the slope of the best fit line is positive.
The value ofr must be between -1 and 1, inclusive

The linear correlation coefficient for this data set is 0.96.
(0,23), (1,22), (2, 27), (2, 28), (5, 35)
Use the table of critical values of the linear correlation coefficient to determine if there is a
significant linear correlation between the x and y variables for alpha=0.05.
No, because the critical value is 0.878 and 0.96 is greater than that.
No, because the critical value is 0.950 and 0.96 is greater than that.
O Yes, because the critical value is 0.950 and 0.96 is greater than that.
Yes, because the critical value is 0.878 and 0.96 is greater than that.
