velikii [3]

Answer:

Step-by-step explanation:

Frequency table for the height of the seedlings,

Height (in inches) Number of seedlings

$\frac{1}{2}$ 2

$\frac{3}{4}$ 4

$\frac{5}{8}$ 2

$\frac{7}{8}$ 2

Now we can draw the line plot as attached.

Average height of the seedlings = $\frac{2(\frac{1}{2})+4(\frac{3}{4})+2(\frac{5}{8})+2(\frac{7}{8})}{2+4+2+2}$

= $\frac{1+3+1.25+1.75}{10}$

= $\frac{7}{10}$
