Question

Two economists ranked 10 franchises by profitability potential. The sum of squared differences in their rankings is 26. Check to see if their rankings are correlated by calculating the Spearman Coefficient of Rank Correlation. 

1. Calculated rs .  

2. At alpha =1% and a two-tail test, what is the critical value of rs .  

3. Does the correlation coefficient differ significantly from zero? (Y or N)    

4. Is the correlation positive? (Y or N)
