the least squares best fit line for the number of years in college X and the income level Y is y=11.9 + 3.46X Given that standard errors of X and Y are Sx =1.8 and Sy= 7.2, what is the correlation coefficient

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer is because 4×10=40

and 98×4= is 392
