diameter is 15 meters then radius is 15/2 = 7.5 meters
so the amplitude is 7.5 m and height will oscillate with amplitude 7.5 m above and below the center.
midline of the oscillation will be 7.5 m
the wheel.take 8 minutes to complete revolution then it means the height will oscillate with a period of 8 minutes
Not entirely, it could be an isoceles triangle (a triangle which all sides are different lengths) but there is still a possibility.

Answer:
C. The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.398, when, in fact, the proportion is 0.398.

The proportion is 0.398

The proportion is less than 0.398
If in actual fact the proportion is 0.398, then the president must not reject the

.
This is a correct decision.
If in actual fact the proportion is 0.398, and the president rejects the

, then a type I error is committed.
The correct choice is C.
