Question

Find the mean, median, and modes of the data set: 91, 93, 89, 97, 89, 98, 94, 93.(2 points)
The mean is ___.
The median is ___.
The first mode in the data set is ___.
The second mode in the data set is ___.

Answer 1

wrong

Answer 2

The mean is 93.
The median is 93.
The first mode in the data set is 89.
There is no second mode in the data set.

Answer 3

Apologies for the error. Let me recalculate the mean, median, and modes:

Mean:
(91 + 93 + 89 + 97 + 89 + 98 + 94 + 93) / 8 = 92

Median:
Putting the data in order: 89, 89, 91, 93, 93, 94, 97, 98
There are 8 numbers, so the median is the average of the 4th and 5th numbers: (93 + 93) / 2 = 93

Modes:
The modes in this data set are 89 and 93.

Therefore, the correct answers are:
The mean is 92.
The median is 93.
The first mode in the data set is 89.
The second mode in the data set is 93.
