Answer:
24 and 30.
Explanation:
To find the mode of the results, which represents the value that appears most frequently, we can follow these steps:
Organize the measurements in ascending order: 18, 18, 21, 24, 24, 24, 27, 30, 30, 30.
Count the frequency of each measurement:
18 appears twice.
21 appears once.
24 appears three times.
27 appears once.
30 appears three times.
Identify the measurement(s) with the highest frequency. In this case, both 24 and 30 appear three times, which is the highest frequency among all the measurements.
Therefore, the mode of the results is 24 and 30.
In summary, the mode of the measurements is 24 and 30, as they both appear most frequently, each occurring three times.
