Answer:
I think it's choice B and D
Step-by-step explanation:
they both are a straight line and would both have a slope of zero. between point A and D is a slope obviously but D and F would not be the same slope because the line gets steeper. that's how I look at it. I'm pretty sure that's it.

Answer: 0.512, 0.020, 0.012, 0.002
Step-by-step explanation:
To put these decimals in the order from greatest to least, we first need to make sure they all have the same place values.
0.012, 0.002, 0.020, 0.512
Now that they have the same place values, we can see which is bigger.
0.512, 0.020, 0.012, 0.002
Answer:
The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.
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 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 5.4 - 0.04 = 5.36 years.
The upper end of the interval is the sample mean added to M. So it is 5.4 + 0.04 = 5.44 years.
The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.
