In this question given the time and frequencies.
00:07
So time is 0, 2, 4, 3, 6 and frequencies are 5, 7, 2, 9, 1.
00:18
So, first question is find mean.
00:22
The equation for finding mean is summation x -i -f -5 divided by summation f -5.
00:30
So we have to find xi fi from here.
00:35
So we get 0, 14, 8, 27, 6.
00:42
And we need the summation, that is we get 55 and the summation is 24.
00:50
So substituting here we get 55 by 24.
00:55
That is 2 .29.
00:57
So our mean is 2 .29.
01:03
Second question, find median.
01:06
For finding median, first arrange the frequency table with observation in ascending order and or descending order and accumulate the frequencies.
01:18
Here the time is given us...
