Answer:
- <u><em>A. Both numbers are statistics.</em></u>
Explanation:
The number 94.6 is an average measure from a <em>sample</em>. It is the mean of a sample.
The number 65.3 is the standar deviation of a sample.
Then, thus numbers are used to estimate the values of the population.
The true mean and the standard deviation of a population are constant numbers; many times unknown (specially when the population is too big). As ,those values are <em>parameters</em> of the population, regardless they are known or not.
When, they are not known, the statistician must estimate them. The statistician does it using samples (one or more). Such <em>estimated values are not parameter but statistics.</em>
Statistics are values for a sample and may (in general will) vary from sample to sample, while the parameters, which belong to the population are fixed values.
