Help me with a quick question?

Answer 1

are you looking for a number or is it a word answer

Answer 2

hint:
we have to apply the formula which gives the value of the coefficient r

Answer 3

@Michele_Laino Can you help?
@red_x I THINK a number.

Answer 4

Here is your formula:
\[r = \frac{{\sum {\left( {{x_i} - \bar x} \right)\left( {{y_i} - \bar y} \right)} }}{{\sum {{{\left( {{x_i} - \bar x} \right)}^2}\sum {{{\left( {{y_i} - \bar y} \right)}^2}} } }}\]

Answer 5

where \[{\bar x},\; {\bar y}\] are the mean values of x and y respectively

Answer 6

@Michele_Laino 0.866?

Answer 7

Sincerely I don't made the computation, but if you have applied that formula correctly then, you got the right answer

Answer 8

generally the value of r is close to 1, so I think you got the right result
