Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0):
Alternative hypothesis (H1):
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no

Explanation
a. The volume of a cone with radius r and height h is . If the radius is doubled, the new volume will be
, which is equal to
. This means that the volume is multiplied by 4.
b. The volume of a cone with radius r and height h is . If the height is doubled, the new volume will be
, which is equal to
. This means that the volume is multiplied by 2.
