Please label all answers clearly

The following is a set of data from a sample of n= 11 items. Complete parts (a) through (c). 151012511 6316 19 13 14 Y 45 30 36 15 33 18 9 4857 39 42 a. Compute the sample covariance. (Round to three decimal places as needed.) b. Compute the coefficient of correlation. not round until the final answer. Then round to three decimal places as needed.) c. How strong is the relationship between X and Y? Explain. A. B. ° C. D. X and Y have a strong positive correlation because as X increases, Y tends to increase also. X and Y have no correlation. X and Y have a perfect negative correlation because all points fall on a straight line with a negative slope. X and Y have a perfect positive correlation because all points fall on a straight line with a positive slope.

Explanation / Answer

Here Y is 3 times of X in every value, so relatinship is perfectly positve linear

So, coefficient of correlation is 1

Sample covariance 73.255 (from excel calculation)

c) Option D is Correct
