<h2>
Step-by-step explanation: </h2>
We know that the dot plot is nothing but the representation of outcomes of a experiment where the dots represent the value of each outcome.
and the total number of dots represent the total number of items which are studied or recorded.
Here, the total number of trials that are recorded is equal to the total number of dots in the dot plot i.e. the total frequency of the set.
The data frequency table is as follows:
Value Frequency
15 2
17 3
19 2
20 2
21 1
23 4
24 1
25 3
Total frequency= 2+3+2+2+1+4+1+3=18
Hence, the answer is: 18
