Answer :
Final answer:
The mean and standard deviation for the tread life of snow tires, given the options, would be likely be b) Mean = 29000 miles, Standard Deviation = 2500 miles. This represents an average tread life of 29000 miles, with a typical variation of 2500 miles.
Explanation:
The question asks about the mean and standard deviation of the tread life of snow tires.
The mean represents the average value while the standard deviation is a measure of the variability or dispersion of a set of values.
In the context of these snow tires, the mean would represent the average tread life of the tires while the standard deviation would show how much the tread life varies from the average.
Given the choices, the correct answer would be b) Mean = 29000 miles, Standard Deviation = 2500 miles.
This is because a mean of 29000 miles indicates the average tread life and a standard deviation of 2500 miles represents how much the tread life tends to deviate from the average.
A standard deviation larger than the mean (option a and d) would not make sense as it would imply that the data is spread out over a very large range, which is not typical for something like tire tread life.
Remember, the mean is the average result you would expect and the standard deviation tells us how much we can expect that result to vary.
