A study was conducted into the relationship between the age in years of a person and their average weekly after tax income. You have been supplied with the following information regarding a regression model that had been developed as part of the study. Regression analysis
sample intercept 657.16
sample slope 1.87

A particular observed value from the data is:

x = 22, y = 904.59

Calculate the residual of this observed value of the response variable.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

a reflection across the x axis and a 90 degree rotation left and right.
