Question

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) Responses mean = 9.3, median = 8, mode =13 mean = 9.3, median = 8, mode =13 mean = 8.5, median = 10, mode = 13 mean = 8.5, median = 10, mode = 13 mean = 9.3, median = 10, mode = 13 mean = 9.3, median = 10, mode = 13 mean = 8.5, median = 10, mode = 8

Answer 2

The mean is calculated by adding up all the values in the data set and then dividing by the number of values. For this data set, the mean is (15+13+9+9+7+1+11+10+13+1+13)/11 = 9.3.
The median is the middle value when the data set is arranged in numerical order. In this case, the data set is already in order, so the median is the middle value, which is 9.
The mode is the value(s) that appear most frequently in the data set. In this case, the number 13 appears three times, which is more than any other number, making it the mode.

So the correct answer is mean = 9.3, median = 9, mode = 13.
