To find the mean, we add up all the numbers and divide by the total number of values.
Mean = (15 + 13 + 9 + 9 + 7 + 1 + 11 + 10 + 13 + 1 + 13) / 11 ≈ 9.3
To find the median, we need to arrange the data set in order from least to greatest and find the middle value.
Arranging the data set in order: 1, 1, 7, 9, 9, 10, 11, 13, 13, 13, 15
The middle value is 10, so the median is 10.
To find the mode, we find the value(s) that appear most frequently in the data set.
The number 13 appears 3 times in the data set, which is more frequent than any other number.
So, the mode is 13.
Therefore, the correct answer is:
• mean = 9.3, median = 10, mode = 13
Find the mean, median, and mode of the data set. Round to the nearest tenth.
15, 13, 9, 9, 7, 1, 11, 10, 13, 1, 13 (1 point)
• mean = 9.3, median = 8, mode = 13
• mean = 8.5, median = 10, mode = 13
• mean = 9.3, median = 10, mode = 13
• mean = 8.5, median = 10, mode = 8
