Final answer:
A possible data set for the median number of texts sent being 25 could be: 15, 20, 22, 25, 27, 30, 35. The fourth value needs to be 25 to be the median of seven data points.
Step-by-step explanation:
The question asks for a possible data set for seven students if the median number of texts sent per day is 25. A median is the middle number in a data set when the numbers are arranged in order. Since there are seven students, the fourth value must be 25 to ensure it is the median. The other numbers can vary as long as they do not change the position of the median.
An example data set could be: 15, 20, 22, 25, 27, 30, 35. Here, the fourth value is 25, making it the median. The values before and after can be different but must be in ascending order to maintain 25 as the median.
