Question

chloe compares the growth of plant species a and b.

part a
what do the box plots tell you about the growth of a typical plant of each species?
choose the correct response.

• plant b typically grows 1 cm taller than plant a, since the range for plant b is 1 cm greater.
• plant b typically grows 1 cm taller than plant a, since the iqr for plant b is 1 cm greater.
• plant a typically grows 1 cm taller than plant b, since the median for plant a is 1 cm greater.
• plant a typically grows 1 cm taller than plant b, since the range for plant a is 1 cm greater.

Find the median growth for each plant species

\[

$$\begin{aligned} &\text{Median of Plant A} = 6\text{ cm} \\ &\text{Median of Plant B} = 5\text{ cm} \end{aligned}$$

\]

Compare the typical growth values

\[

$$\begin{aligned} &\text{Difference} = 6\text{ cm} - 5\text{ cm} = 1\text{ cm} \\ &\text{Plant A typically grows } 1\text{ cm taller than Plant B because its median is } 1\text{ cm greater.} \end{aligned}$$

\]

Match with the correct option

\[
\text{Option 3 matches: "Plant A typically grows 1 cm taller than Plant B, since the median for Plant A is 1 cm greater."}
\]
