Answer :
Final answer:
The coefficient of rank correlation for the given data set is approximately -0.98.
Explanation:
The coefficient of rank correlation is a measure of the strength and direction of the relationship between two variables. In this case, we have the data set y: 110, 111, 114, 114, 114, 116, 115, 117. To calculate the coefficient of rank correlation, we can use the formula:
r = 1 - (6 x ∑d^2)/(n x (n^2 - 1))
where r is the coefficient of rank correlation, d is the difference in ranks, and n is the number of data points.
By calculating the differences in ranks and plugging them into the formula, we find that the coefficient of rank correlation is approximately -0.98. Therefore, the correct answer is c.-0.98.
