The mean is ___.
The median is ___.
The first mode in the data set is ___.
The second mode in the data set is ___.
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.
wrong
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.
