In the notation X ~ U(a, b), the letter b stands for:
AThe lowest value of x
BThe mean of the sample
CThe count of the trials
DThe highest value of x
Answer & Solution
Correct answer: D. The highest value of x
1. The uniform distribution is defined by its two endpoints.
2. The notation for the uniform distribution is X ~ U(a, b).
3. In that notation a is the lowest value of x.
4. And b is the highest value of x.
