A continuous uniform distribution has a lower bound of zero and f(X)=2. What is P(X≤0.25)?
Your answer: A was incorrect. The correct answer was D) 0.50.
The height of a pdf for a continuous distribution is f(X). The area under the pdf must equal one; therefore, the length of the pdf is 0.5. Since the lower bound is zero, the upper bound is 0.5, P(X≤0.25)=0.5.
what does it mean? thanks! |
