the scatter plot,

the question.

- welshfella

The observed values are the actual dots on the graph while the predicted values are the corresponding point on the line. The residual is the difference between these 2 values.

so how would i do it

- welshfella

Read the values off the graph
what is the plotted point for monthly heating cost for 25.4 degrees?

- anonymous

51.00

- welshfella

right - its on the table as well as the graph
now you cant read the cost accurately from the line so use the equation

- anonymous

but with the equation im confused. wht am i supposed to finding from the eqaution?

- welshfella

monthly cost y = -1.1 x + 90.51
replace x by 25.4 and calculate y

- anonymous

62.57

- welshfella

y = -1.1 * 25.4 + 90.51
it should come to approximately 62

- welshfella

- right that was fast

- anonymous

should i put 62 or 62.57

- welshfella

put 62.57

- anonymous

okay i did that

- welshfella

now the residual is the difference
to be honest i'm not sure which one is subtracted - I think its 62.57 - 51.00

- anonymous

okay 11.57

- welshfella

yes

- welshfella

- the cost was less than expected so that's 11.57 in your pocket - right?

- anonymous

yeah. so i did the same for the bottom question

- anonymous

would you mind helping me with another?

- welshfella

ok but i have to go in 10 minuets

- anonymous

ok illl post it fast

predicted score for no time studying is
y = 3.83(0) + 15,68

- anonymous

so 15.68?

- welshfella

for 1 hour of study
y = 3.83 + 15.68
answer = this value - value for no stusying

- welshfella

for 12 hours of study
y = 3.83(12) + 15.68

- anonymous

so my answers are 15.68
3.84
and 61.65

- welshfella

second one is 3.83
yes

- welshfella

- other 2 are right

- welshfella

gotta go now
hoped you have learned something
