Given:
Step-by-step explanation
Step 1.
Using scatterplot in part 
, value of 
is 
, value of is So, taking square root of , the correlation coefficient is 
.
, the correlation coefficient is .The sample size of the given data is 
.
.So, to test the significance of the correlation coefficient, the degree of freedom for the given data is written below:
Referring to table for 
critical values of the sample Correlation Coefficient of this textbook, the critical value corresponding to 
degrees of freedom is 
.
critical values of the sample Correlation Coefficient of this textbook, the critical value corresponding to degrees of freedom is .The value of Correlation Coefficient 
does lie between the positive 
and negative 
critical values.
does lie between the positive and negative critical values.Unlock all Textbook Solutions
