Class interval 0-50. 50-100. 100-150
Frequency. 17. 35. 43
Class interval. 150-200. 200-250. 250-300
Frequency 40. 21. 24
Answers
Arithmetic mean of First frequency table is 88.68.
Arithmetic mean of Second frequency table is 215.6.
Step-by-step explanation:
We are given the following frequency distribution table below;
Class Interval X Frequency (f)
0 - 50 25 17 425
50 - 100 75 35 2625
100 - 150 125 43 5375
= 95 = 8425
Now, the mean of frequency distribution table is given by the following formula;
Mean, =
= = 88.68
- Similarly, we are given another frequency distribution table below;
Class Interval X Frequency (f)
150 - 200 175 40 7000
200 - 250 225 21 4725
250 - 300 275 24 6600
= 85 = 18325
Now, the mean of frequency distribution table is given by the following formula;
Mean, =
= = 215.6
