The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
Answer:
$450
Step-by-step explanation:
We know that the washer costs $51 more dollars than the dryer.
The washer costs x+51
The dryer costs x
So to simplify this we can do this equation:

Substitute and simply the equation, and you should get this:
2x=900
x=450
Hope this helps! :)
