Answer:

20

Step-by-step explanation:

Since Tristan tracks customer counts at the store each hour on Saturday.

His recorded data for the first seven hours consists of 15, 23, 12, 28, 20, 18, and 23.

There are 7 data points and placing them in ascending order yields 12,15,18,20,23,23,28

The median = central entry -20

Should an additional entry be made, we will have two central entries, and the median would then represent their average.

Consequently, to keep the median consistent, the number of customers during the eighth hour should be 20

Thus, the answer is 20

First, arrange the numbers in ascending order:
12, 15, 18, 20, 23, 23, 28
The median value is the central number of this sequence—20.
