A curve has area 0.622 to the left of 65 and area 0.378 to the right of 65. Could this curve be a density curve for some variable? Explain your answer. Choose the correct answer below. OA. The curve could not be a density curve because the total area under the curve is less than 1. B. The curve could be a density curve because the total area under the curve is equal to 1. OC. The curve could not be a density curve because the total area under the curve is greater than 1. OD. There is insufficient information to determine if this curve could be a density curve for some variable.
