Question

a grocery store buys oranges from two different farmers. the mean weight of farmer as oranges is 8 oz. the mean weight of farmer bs oranges is 9.1 oz. the mad of both data sets is 2. what can you infer about the two sets of oranges?

  • the mad is large.
  • the data sets are very different.
  • the variabilities of the sets of oranges are similar.
  • the mean is small.

<reasoning>

Compare the Mean Absolute Deviation (MAD) of both data sets

\[
\text{MAD of Farmer A's oranges} = 2
\]
\[
\text{MAD of Farmer B's oranges} = 2
\]

Relate MAD to variability

\[
\text{MAD} = \text{Measure of variability}
\]
\[
\text{Equal MAD values} \implies \text{Similar variabilities}
\]

Evaluate the given options

\[
\text{Option 3 matches the conclusion: "The variabilities of the sets of oranges are similar."}
\]
