Answer:
2. The standard deviation of the distances in kilometers is larger.
Step-by-step explanation:
Let us assume the distance of car travel in miles is x
And, the distance of car travel in kilometers is y
Given that
1 mile = 1.6 km
That means
y = 1.6x
Therefore
The standard deviation of y = 1.6 × (standard deviation of x)
The above equation represents
The standard deviation of y > standard deviation of x
hence, the correct option is 2.
