12. Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people answered that they generally sell three cars; nineteen generally sell four cars; twelve generally sell five cars; nine generally sell

Answer 1

To find the mode (the value that appears most frequently) in a data set, you can follow these steps:

1. Organize the data in ascending order. In this case, the data is as follows:
3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5

2. Count the frequency of each value. Count how many times each number appears in the data set:
- The number 3 appears 4 times.
- The number 4 appears 8 times.
- The number 5 appears 11 times.

3. Identify the value with the highest frequency. In this case, the number 5 appears most frequently, with a frequency of 11.

Therefore, the mode of this data set is 5, which means that among the randomly selected car salespersons, the majority of them typically sell five cars in one week.
