the above class intervals are selected as 60 packet or more but less than 70 packets,70 packets or more but less than 80 packets....etc<br />
<br />
1.They ask me to find down the model class of this frequency distribution,<br />
<br />
2.taking the mid value of the class interval 110-120 as the assumed mean,find the mean number of packets of milk powder sold per day during this period<br />
<br />
3. Assuming that this sales pattern continues in the future,estimate the stock of packets of milk powder needed for 60 days.<br />
<br />
can anyone tell me the method of finding or any websites.<br />
