I don't understand what your asking
Considering the situation described, the hypothesis tested are given as follows:
- The null hypothesis is
- The alternative hypothesis is
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:
At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

D.
None of the above. Because your expression would be, 2 + 0.75 x 6.
Hope it helps. ;)
The midpoint, where the rest area is, will just be the average of the coordinates of Springfield and Columbus.
Rest Area=((1+7)/2, (-4+1)/2)
Rest Area=(4, -1.5)
The distance between the two cities can be found using the Pythagorean Theorem, which used in the manner is often referred to as the "distance" formula between two points.
d^2=(x2-x1)^2+(y2-y1)
d^2=(7-1)^2+(1--4)^2
d^2=36+25
d^2=61
d=√61 and we are told that each unit is equal to 5.38mi so the distance from Springfield to Columbus is:
D=5.38√61 mi
D≈42.02mi (to nearest hundredth of a mile)
