0.9067

Step-by-step explanation:

The formula used for correlation coefficient is given by,

where = Sample Covariance between X and Y

= Standard Deviation of X

= Standard deviation of Y

Sample Covariance can be calculate using formula:

where, = Mean of X

= Mean of Y

Standard Deviation is the square root of sum of square of the distance of observation from the mean.  

where, is mean of the distribution.

Calculating all values:  

= -1.111

= 4.939

= 954.889

= 16.534

= 119.639

Now, Putting all values in Formula of Co rrelation Coefficient. We get,

= 0.9067

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
