Question
In studying the relationship between income and time spent exercising, suppose you computed r=−0.052 using n=19data points. Using the critical values table below, determine if the value of r is significant or not.
df CV (+ and -) df CV (+ and -) df CV (+ and -) df CV (+ and -)
1 0.997 11 0.555 21 0.413 40 0.304
2 0.950 12 0.532 22 0.404 50 0.273
3 0.878 13 0.514 23 0.396 60 0.250
4 0.811 14 0.497 24 0.388 70 0.232

10 0.576 20 0.423 30 0.349    

Select the correct answer below:

 
a. r is significant because it is between the positive and negative critical values.
 
b. r is not significant because it is between the positive and negative critical values.
 
c. r is significant because it is not between the positive and negative critical values.
 
d. r is not significant because it is not between the positive and negative critical values.
