c. you reject a null hypothesis that is true
Step-by-step explanation:
We need to remember the following concepts
Error type I: Is an error associated to the probability of reject a null hypothesis when it is actually true
Error type II: Is an error associated of not rejecting a null hypothesis when the alternative hypothesis is the true
And the best answer for this case would be:
c. you reject a null hypothesis that is true
Answer:
Therefore the rate change of height is 
m/s.
Step-by-step explanation:
Given that a vertical cylinder is leaking water at rate of 4 m³/s.
It means the rate change of volume is 4 m³/s.
The radius of the cylinder remains constant with respect to time, but the height of the water label changes with respect to time.
The height of the cylinder be h(say).
The volume of a cylinder is 
Differentiating with respect to t.
Putting the value 
The rate change of height does not depend on the height.
Therefore the rate change of height is m/s.
