Answer:
The critical value for the 95% confidence interval is z = 1.96.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
So it is z with a pvalue of 
, so z = 1.96.
The critical value for the 95% confidence interval is z = 1.96.
Answer:
the y intercept is 6
Step-by-step explanation:
Step 1: Add -4x to both sides.
4x+2y+−4x=12+−4x
2y=−4x+12
Step 2: Divide both sides by 2.
2y
/2 =
−4x+12
/2
y=−2x+6
Points (3,6)
x intercept is 3 and y intercept is 6
