Answer:
0.74 to 6.06
Step-by-step explanation:
The groups are independnet,
SE(xh bar-xa bar)=sqrt [sh^2/nh+sa^2/na]=sqrt [10.1^2/80+10.3^2/80]=1.61
At df=157, the t critical is 1.65
90%c.i=(xh bar-xa bar)+-tcritical SE(xh bar-xa bar)
=(25.2-21.8)+-1.65*1.61
=0.74 to 6.06

<u><em>Explanation</em></u>
Current value of the investment is
dollars and 30 years ago, the value of the investment was
dollars.
Suppose, the value of investment today is
times greater than the value of the investment thirty years ago.
So, the equation will be........

Thus, the value of the investment today is 450 times greater than the value of the investment thirty years ago.
ANSWER



EXPLANATION
Since line l is parallel to line m,

because the two angles are vertically opposite angles.

because the two angles are corresponding angles.

because the two angles are alternate exterior angles.
