Seedlings

The meadow was divided into 30 equally large parts, and then how many seedlings were in each part was calculated. It was found that there were no seedlings in six parts. Five parts contained one seedling, twelve parts two seedlings, and seven parts three seedlings. Assess whether the seedlings are randomly distributed in the meadow.

Yes

No

Step-by-step explanation:

$$\begin{gathered} a_1=\frac{1}{30}\doteq 0.0333 \\ {a}_2=\frac{6\cdot 0+5\cdot 1+12\cdot 2+7\cdot 3}{30}=\frac{5}{3}=1\frac{2}{3}\doteq 1.6667 \\ {a}_2>a_1 \\ x=0 \end{gathered}$$
