Question

An experiment to study the effect of new medicine for making the patients unconscious before operation is performed on 50 rats. Each rat was injected with a standard dose and the time taken by each rat to become conscious is noted in minutes (correct upto one decimal point) and the following data were obtained :
45.0 58.2 55.1 52.2 61.7 52.9 70.4 62.5 713 50.1
84.9 60.9 35.4 64.3 75.7 48.5 41.3 53.8 66.8 37.4
32.4 50.7 82.3 71.8 66.4 49.7 51.7 56.0 88.8 64.7
77.9 41.4 52.7 53.4 57.9 51.7 55.6 44.1 85.4 67.3
87.3 52.5 40.7 48.7 60.0 66.0 77.3 46.5 54.3 52.6
Prepare a frequency distribution table from above data.

Answer 1

Step-by-step explanation:

To prepare a frequency distribution table from the given data,

Take class size 10,it is not mandatory;you can choose as per your choice.

45.0 58.2 55.1 52.2 61.7 52.9 70.4 62.5 71.3 50.1 84.9 60.9 35.4 64.3 75.7 48.5 41.3 53.8 66.8 37.4 32.4 50.7 82.3 71.8 66.4 49.7 51.7 56.0 88.8 64.7 77.9 41.4 52.7 53.4 57.9 51.7 55.6 44.1 85.4 67.3

87.3 52.5 40.7 48.7 60.0 66.0 77.3 46.5 54.3 52.6

In class 30-40:37.4,32.4,35.5 are included

$</p><p>\begin{tabular}{|l|l|}</p><p>\cline{1-2}</p><p>Class Interval & Frequency \\ \cline{1-2}</p><p>30-40 & 3 \\ \cline{1-2}</p><p>40-50 & 9 \\ \cline{1-2}</p><p>50-60 & 17 \\ \cline{1-2}</p><p>60-70 & 10 \\ \cline{1-2}</p><p>70-80 & 6 \\ \cline{1-2}</p><p>80-90 & 5 \\ \cline{1-2}</p><p>Total & 50 \\ \cline{1-2}</p><p>\end{tabular}</p><p>\end{table}$

Taking class interval of 10.

Class 30-40(40 not included)

Hope it helps you.
