Question

If mean of the following data is 44 find the missing frequency

Answer 1

The Mean from a Frequency Table. It is easy to calculate the Mean: Add up all the numbers, then divide by how many numbers there are.

let take  some entries

44,45,43,5,x

we have to find x and we know that mean of given data is 44

(44+45+43+5+x)/5=44

x+137=44*5

x+137=220

x=220-137

so missing frequency is 83

x=83

Answer 2

Answer: 186 if frequency r 12,x,6,7,9

Step-by-step explanation:MEAN=12+x+6+7+9/5

44=x+12+6+7+9/5

44×5=x+34

220=x+34

220-34=186=x
