A consumer advocate conducted a test of a popular gasoline additive that was claimed to increase gasoline mileage in cars. For a sample of 15 cars they used the additive and determined how many more miles the car could drive when the additive was added to the gas tank.

For example, a positive 10 would mean that the car drove 10 more miles with the additive whereas a -3 would mean that the car drove 3 fewer miles with the additive.
The table shows a few data values (of how many more miles a car could drive with the additive) along with some summary statistics.

Are there any striking deviations?
A) -5
B) -3
C) 37
D) 65

Answer:

D)65

Step-by-step explanation:

Striking deviations are any values outside the normal trend of the data. The data set has an interquartile range of 22. If you look at the values that are on the low end you see -5, which is close to the next value of -3 as well as Q1 of -2. On the high end you see the value of 65, which is a long way off to the next value of 37 and even further off from Q3 of 20. A striking deviation would be 65
