D: What type of car do the seniors in the local high school prefer to drive?
This is a statistical question because it involves gathering data from a specific group (seniors in a local high school) in order to find an answer. The units for the answer would be the type of car preferred by the seniors, such as sedan, SUV, truck, etc.

Question
Dylan is going fishing. The lengths, in centimeters, of nine earthworms are shown below. He just caught a tenth earthworm that is 9.5 centimeters long. What is the median of the data once the tenth earthworm is included in the data set?
3, 4, 5, 5, 6, 7, 8, 9, 10
Responses
A 6.5
B 6
C 6.65
D 9.59
B 6
To find the median of a set of data, you need to order the numbers from least to greatest and find the middle number.
The ordered set of data is: 3, 4, 5, 5, 6, 7, 8, 9, 10, 9.5
The middle number is 6, which is the median of the data set once the tenth earthworm is included.

The range is Response area
Suppose the value 26 is added to the data set.
The mean decreases by Response area.
The median decreases by Response area.
The mode is Response area.
The range is Response area.
The mean is 34.2
The median is 34
The mode is 34
The range is 33
Suppose the value 26 is added to the data set.
The mean decreases by 0.4.
The median stays the same.

answer choices 0.7 34 unchanged 33 0.50 33.7 34.5
The mean is 34.2
The median is 34
The mode is 34
The range is 33
Suppose the value 26 is added to the data set.
The mean decreases by 0.4.
The median stays the same.
The mode is still 34.
The range increases by 8 to 41.
Therefore, the answers should be:
The mean decreases by 0.4. - 0.4
The median decreases by unchanged. - unchanged
