Sum of squares of differences in ranks-25.5, n=10, an item 20 is repeated 4 times and another item 22 is repeated 3 times in case of X series and 24 is repeated 2 times in case of y series, coefficient of rank correlation is a) 0.70 b) 0.80 c) 0.85 d) none

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

what is the information provided?

step-by-step explanation:

answer: 0.26
