Answer:
the residual is 0.2032
Step-by-step explanation:
The regression line has been given as:
Y^ = 0.00753X-0.06759
The paired observation for X is (31, 0.369)
The value of X is the empathy score under subject 15 = 31
The value of the brain activity under subject 15 is 0.369
So we have y^ = 0.00753(31) - 0.06759
= 0.1658
Then the residual = y - y^
= 0.369 - 0.1658
= 0.2032
Therefore the residual is 0.2032

Where,
predicted value of lead content when traffic flow is 15.
Calculating thet-critical value
The lower predicted value 
When 
of CI use as the expected lead content:
Part A Answer: Company A: (Wx6)+12 Company B: (Wx5)+15
The varible used was W because windows start with a W i chose this as the variable because it is for the certain NUMBER of windows.
Part B:Company A: 8x6=48+12=$70 for 8 windows and service charges.
Company B:8x5=40+15=$55 for 8 windows and service charges.
Company B would charge less for 8 windows.
Part C:My work for Company A: 6x6=36+12=$48 for 6 windows and service charges
My work for Company B: 6x5=30+15=$45 for 6 windows + service charges
$48-$45=$3
Answer for Part C: $3 would be saved by using the services of Company B instead if Company A to clean 6 windows.
