Which of the following random variables (X) are continuous? Select all that apply. X is the number of petals on a randomly chosen daisy X is the number of daisies found in a randomly chosen grassy area 1 square meter in size X is the average number of petals per daisy computed from all the daisies found in a randomly chosen grassy area 1 square meter in size X is the stem length in centimeters of a randomly chosen daisy The distribution for the number of patients that a doctor sees per day is shown below. What is the notation for this distribution?Explanation / Answer
Continuous random variables are variables which can contain decimals in their values.
A - Cannot be a continuous random variable becuase, it can take only a whole numbers. The variables which has whole numbers are defined as discrete.
B - Cannot be a continuous random variable becuase, it can take only a whole numbers. That is we cant say that there are 4.5 daisies found.
C - Average number of petals is a continuous random variable. Since we take the average nuumber of petals, we cannot expect the average to be whole number.
D - Stem length in centimeters is a continuous random variable. This can be measured and the decimal values are meaningful
