Answer:

the correlation coefficient is 0.1786

Explanation:

To calculate the correlation coefficient between the returns of investments A and B we have to find the value of C in the following equation:

covariance of returns on A and B = correlation coefficient (we will call this C) x standard deviation A x standard deviation B

0.006 = C x 0.21 x 0.16 = 0.0336C

C = 0.006 / 0.0336 = 0.1786
