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
To find the mean, we sum up all the numbers in the data set and divide by the total number of numbers in the set.
Mean = (15 + 13 + 9 + 9 + 7 + 1 + 11 + 10 + 13 + 1 + 13) / 11 = 9.3 (rounded to the nearest tenth)
To find the median, first we need to arrange the numbers in order from least to greatest:
1, 1, 7, 9, 9, 10, 11, 13, 13, 13, 15
Since the number of values in the set is odd, the median is the middle value, which is 10.
The mode is the number(s) that occur(s) most frequently in the data set. In this case, 13 occurs 3 times, which is more than any other number in the set.
Therefore, the correct answer is:
mean = 9.3, median = 10, mode = 13
