Given the data as shown in the table below

X Y
7 0.4
10 0.5
8 0.37
5 0.34
11 0.53



a) Compute �¯ the following values:
�-1= 

�¯=  . (Round your answer to 2 decimal places.)

�¯=  . (Round your answer to 2 decimal places.)

��=  . (Round your answer to 2 decimal places.)

��=  . (Round your answer to 2 decimal places.)


b) Use the formula

�=1(�-1)����[(�1-�¯)(�1-�¯)+(�2-�¯)(�2-�¯)+(�3-�¯)(�3-�¯)+(�4-�¯)(�4-�¯)+(�5-�¯)(�5-�¯)]

with computed values from part (a) to calculate the correlation coefficient:
�=  . (Round your answer to 6 decimal places.)
