Machine 2: 310, 309, 314, 311, 309, 314.5, 312.5, 310
Machine 3: 309, 310.5, 313.5, 315.5, 310, 311, 312, 309.5
Which statement is true about the mean output of the three machines?Answer:
a. Machine 1 has the highest
b. Machine 2 has the highest
c. Machine 3 has the highest
d. All three machines have the same mean

do you know what is mean output?
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
Ok... a mean output is the average output.. Do you know how to find the averages?
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
ok... averege is the = total sum divided by total number consider in your exam you have 2 papers... in one paper you got 40 out of 50 and in othr paper you got 42 out of 50... then using the concept of avrages can you just tell me what is your average mark?

Rosh007Best ResponseYou've already chosen the best response.1
..... can you just tell me what steps you have done?

skittles223Best ResponseYou've already chosen the best response.0
i added them all up and divided by how many numbers was there which was 4
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
Your method is correct.. but answer need correction here only we have two papers..then how the total number is 4?
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
or 91 is the answer
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
can you say how you got 91 and 41 ?
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
cause the 91 i got by adding the 40 and the 50 and the 42 and the 50 and then dividing it by 2 and i got 91 then i just added the 40 and 42 and divided it by 2

Rosh007Best ResponseYou've already chosen the best response.1
what you think which is more accurate.... first case you added 4 numbers (which makes total number is 4) second case you added 2 numbers (which makes total number 2)
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
but can we go ahead and get to my question so i can get this done plz
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
sure.. now how many bags are there?
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
so that is what your total numbr is.. now what you need to do to find the mean output?
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
how do you do that
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
remember mean output is the average output..... you need to find the avrage output of each machine.... you have the total number of bags that each machine process and you know each bages weight..now you need to find the average of each machines output separatly and compare the results to obtain answer..any clue... think twice?:)

Rosh007Best ResponseYou've already chosen the best response.1
ok... what is the machine 1's average output
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
i added up all the numbers in machine 1 and then i got 2487 then i divided it by 8 and got 310.7

Rosh007Best ResponseYou've already chosen the best response.1
exactly... but i think you missd to add 0.5s... please add and verify your answer

Rosh007Best ResponseYou've already chosen the best response.1
309+ 311.5+313+310+308+314+312+310.5 =?
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
when you just add them
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
yes.. now find average
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
yup... you got the average output of machine one.... congrads now find the averag output of machine 2
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
2490 before u divide for machine 2 right
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
so average or mean output of machine 2 is ?
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
yes.. can you give 2 decimal digit answer
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
means after decimal point two more numbers (which incrases the precision of your answer)
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
Exactly.... well done...... ... in this case this answer (311.2) is sufficient but it won't b in another case where we require more precision.. ok.... Can you give me the mean out out of machine 3 then?
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
***mean output of machine 3
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
give two or three digits after decimal point
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
the third machine has a sum of 2491 before dividing
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
the mean out put of machine three is 311.375
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
Yes.... yess... you got the mean output of alll your machines... now rad the question and tell me what is the correct answer?
 one year ago

skittles223Best ResponseYou've already chosen the best response.0
machine three has the highest because machine 1 only has 311 machine two only has 311.25 and machine three has 311.375
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
yup.... congratulations again......... averages or mean is ok for you now :)
 one year ago

Rosh007Best ResponseYou've already chosen the best response.1
also... there are som simple tricks to find mean values... you may study later
