The 99% confidence interval ranges from 53.73 to 56.27 hours.
Answer: Is 6.4
Step-by-step explanation: I hope I helped in some way shape or form.
The gradient of y axis is zero. Since the line is parallel to y axis, its gradient is also zero. This
y=mx+c
Where m is the gradient;
y=(0)x+c
y=c
Replacing for y and x;
0=0(-4)+c
c=0
