Question

if £(x-X)(y-Y)=954
standard deviation of x is 21.5
standard deviation of y is 10.61
if r = 0.524 find n=?​

Answer 1

Step-by-step explanation:

£(x-X)(y-Y)=954 standard deviation of x is 21.5 standard deviation of y is 10.61 if r = 0.524 find n=?. Add answer.

Answer 2

Answer:

as r=£(x-X)(y-Y)/n(Sd of x)(Sd of y)

Step-by-step explanation:

so r=954/n(21.5)(10.61)

n=954/(0.524)(21.5)(10.61)

n=8
