Answer:
The confidence interval for 90% confidence would be narrower than the 95% confidence
Step-by-step explanation:
From the question we are told that
The sample size is n = 41
For a 95% confidence the level of significance is
and
the critical value of
is 
For a 90% confidence the level of significance is
and
the critical value of
is 
So we see with decreasing confidence level the critical value decrease
Now the margin of error is mathematically represented as
given that other values are constant and only
is varying we have that

Hence for reducing confidence level the margin of error will be reducing
The confidence interval is mathematically represented as

Now looking at the above formula and information that we have deduced so far we can infer that as the confidence level reduces , the critical value reduces, the margin of error reduces and the confidence interval becomes narrower
Answer:
A) x > 7
Step-by-step explanation:
Since it's more than, the inequality would be >
Since it's >, that means it's an open circle
So,
x > 7

Step-by-step explanation:
Answer:
y=-1/8y+1
Step-by-step explanation:
flip the equation, then add -8 to both sides to cancel out the +8 on the left, then divide sides by -8Let's solve for x.
y=−8x+8
Step 1: Flip the equation.
−8x+8=y
Step 2: Add -8 to both sides.
−8x+8+−8=y+−8
−8x=y−8
Step 3: Divide both sides by -8.
