There is a relationship between confidence interval and standard deviation:

Where

is the mean,

is standard deviation, and n is number of data points.
Every confidence interval has associated z value. This can be found online.
We need to find the standard deviation first:

When we do all the calculations we find that:

Now we can find confidence intervals:

We can see that as confidence interval increases so does the error margin. Z values accociated with each confidence intreval also get bigger as confidence interval increases.

Is there’s more to this question?
Answer: minimum hourly wage is $8.75
Step-by-step explanation:
To get the minimum hourly wage, we divide $350 by 40hrs
= $350 ÷ 40
= $8.75
Answer:
(3,4)
Step-by-step explanation:
The amount of steps applied from the reflection line to the point would be also applied inversely to the image point (after reflection).
From y=x to (4,3), it goes 1 down and also goes 1 right. (NOTE: It does not go down and right. Instead, it goes <em>either</em> down and right)
So now inverse that to make 1 up and also going 1 left.
To add fractions, first convert them to have equal denominators.
3/4= 9/12 (multiply both sides by 3)
2/3= 8/12 (multiply both sides by 4)
From here, add the numerators while keeping the denominator.
9/12+ 8/12= 17/12
Final answer: 17/12 or 1 5/12
