Area under the curve is given by which function?
AThe correlation formula
BThe cumulative distribution
CThe probability density
DThe regression equation
Answer & Solution
Correct answer: B. The cumulative distribution
1. Two related functions describe a continuous distribution.
2. The curve itself is the probability density function.
3. Area under the curve is given by a different function.
4. That function is the cumulative distribution function, abbreviated cdf.
