Two different plants are producing concrete for the same job. Samples taken during $7$ days from concrete produced in Plant A show that this plant produces concrete with average compressive strength of $35$ MPa and a standard deviation of $4\mathrm{.}4$ MPa while samples for $7$ days from Plant B produce an average compressive strength of $32\mathrm{.}5$ MPa and a standard deviation of $1\mathrm{.}1$ MPa.

Which statement seems to be true?

Group of answer choices

Plant B produces more uniform and less variable material.

Plants seem to have similar production variability.

There is not enough data to draw conclusions on production variability.

Plant A prodcudes more uniform and less variable material.
