To check: Whether the given statement “If the raw data includes 25 values, and the class includes 3 of these values, the relative frequency of this class is 12%” is true or false.
Answer to Problem 1RE
The given statement “If the raw data includes 25 values, and the class includes 3 of these values, the relative frequency of this class is 12%” is
Explanation of Solution
Definition used:
The relative frequency of a given data is found by dividing the frequency by the total number of data.
Calculation:
The given statement is “If the raw data includes 25 values, and the class includes 3 of these values, the relative frequency of this class is 12%”.
From the given statement, 25 is the total number of data and 3 is the frequency.
Hence, the relative frequency is given by,
Therefore, the given statement “If the raw data includes 25 values, and the class includes 3 of these values, the relative frequency of this class is 12%” is
