Q2: “If the coefficient of correlation between two variables is zero, it does not mean that the variables are unrelated”. Comment. Find Karl Pearson’s correlation coefficient between age
and playing habits of the following students:
Age (Years) 15 16 17 18 19 20
No. of Students 250 200 150 120 100 80
Regular Players 200 150 90 48 30 12
Also calculate the probable error and point out if coefficient of correlation is significant.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
