Question

This table shows 10 observations of a pair of variables (x,y). The variables x and y are positively correlated, with a correlation coefficient of 0.977. Find the slope, b, of the least squares regression line, y=ax+b, for these data:
X 1 2 3 4 5 6 7 8 9 11
Y 2 4 5 8 9 12 13 14 15 16

Answer 1

urgent help

Answer 2

\[\sum_{2}^{16}Y=a*\sum_{1}^{11}X +nB\]

Answer 3

put the values in it to get an equation\[\sum_{?}^{?}XY=a*\sum_{?}^{?}X^2+b \sum_{?}^{?}X\]

Answer 4

thank you

Answer 5

:)

Answer 6

the key word you have there is
CORRELATION
just plot the points

approximate the slope

Answer 7

no your super wrong you have to actually workit out

Answer 8

i didnt even understand the formula that other dude gave me.. sorry dude

Answer 9

the other formula was
series if you gone through or done that

Answer 10
