Answer:
13 and 34
Explanation:
The mode of a set of data is the number that appears the most amount of times. In order to find the mode of this set of data, we first start by ordering the numbers from least to greatest.
13, 13, 26, 34, 34, 41, 53, 61, 69
Now, let's identify the number(s) that appear the most in our set of data.
13 and 34 are the only numbers that appear twice, and therefore are the modes.
