Question

For a random sample of 600 randomly selected car batteries, it was found that their output had a mean of 11.9 volts and a standard deviation of 1.8 volts.

____= 600 car batteries

____ = 11.9 volts

____ 1.8 volts

Answer 1

`n = 600` car batteries represent the sample size selected

`\bat X = 11.9` volts represent the sample mean from the sample selected

`s = 1.8` represent the sample deviation from the sample selected

Explanation:

For this case we know that the sample size is 600 randomly selected car batteries.

The sample mean is 11.9 volts and the deviation is 1.8 volts.

So then we can answer the question:

`n = 600` car batteries represent the sample size selected

`\bat X = 11.9` volts represent the sample mean from the sample selected

`s = 1.8` represent the sample deviation from the sample selected
