Final answer:
The mean of the set is 38.22, the median is 34, the modes are 13 and 34, and the range is 56.
Step-by-step explanation:
To find the mean of a set of data, add up all the numbers and divide by the total number of values. For this set, 53 + 13 + 34 + 41 + 26 + 61 + 34 + 13 + 69 = 344. There are 9 numbers in the set, so the mean is 344 / 9 = 38.22 (rounded to two decimal places).
To find the median, arrange the numbers in ascending order and find the middle value. In this case, after sorting the set in ascending order, the middle value is 34.
The mode is the number that appears most frequently in a set. In this set, the numbers 13 and 34 both appear twice, so the modes are 13 and 34.
The range is the difference between the highest and lowest values in a set. In this case, the lowest value is 13 and the highest value is 69, so the range is 69 - 13 = 56.
