The correct Answer is:
To find the frequency of the class interval 310-330 from the given data, we will follow these steps: ### Step 1: Identify the Class Interval We need to focus on the class interval 310-330. This means we will count how many data points fall within this range, including 310 but excluding 330. ### Step 2: List the Given Data The data provided is: - 268, 220, 368, 258, 242, 310, 272, 342, - 310, 290, 300, 320, 319, 304, 402, 338, - 406, 292, 354, 278, 210, 240, 330, 336, - 406, 215, 258, 236. ### Step 3: Count the Observations in the Class Interval Now, we will count how many of these numbers fall within the range of 310 to 330: - 310 (included) - 310 (included) - 319 (included) - 320 (included) ### Step 4: List the Counted Observations The observations that fall within the class interval 310-330 are: 1. 310 2. 310 3. 319 4. 320 ### Step 5: Calculate the Frequency Now, we count the observations: - Total observations in the interval 310-330 = 4 Thus, the frequency of the class interval 310-330 is **4**. ---
