Question

In a ‘tree plantation’ project of a certain school there are 45 students of 'Harit Sena.' The record of trees planted by each student is given below : 3, 5, 7, 6, 4, 3, 5, 4, 3, 5, 4, 7, 5 , 3, 6, 6, 5, 3, 4, 5, 7, 3, 5, 6, 4, 4, 3, 5, 6, 6, 4, 3, 5, 7, 3, 4, 5, 7, 6, 4, 3, 5, 4, 4, 7. Prepare a frequency distribution table of the data.

Answer 1

Step-by-step explanation:

In a ‘tree plantation’ project of a certain school there are 45 students of 'Harit Sena.' The record of trees planted by each student is given below : 3, 5, 7, 6, 4, 3, 5, 4, 3, 5, 4, 7, 5 , 3, 6, 6, 5, 3, 4, 5, 7, 3, 5, 6, 4, 4, 3, 5, 6, 6, 4, 3, 5, 7, 3, 4, 5, 7, 6, 4, 3, 5, 4, 4, 7.

To prepare a frequency distribution table of the data,select the number of entries and take the counting as shown below

$\begin{tabular}{|l|l|}</p><p>\cline{1-2}</p><p>Number of trees & Frequency \\ \cline{1-2}</p><p>3 & 10 \\ \cline{1-2}</p><p>4 & 11 \\ \cline{1-2}</p><p>5 & 11 \\ \cline{1-2}</p><p>6 & 7 \\ \cline{1-2}</p><p>7 & 6 \\ \cline{1-2}</p><p>Total & 45 \\ \cline{1-2}</p><p>\end{tabular}$

Hope it helps you.
