Question

Find the value x such that the data set has the given mean.

101,119,104,111,109,x mean 113
X=?

Answer 1

x = 134

Explanation:

The mean of a data set is calculated as

mean =
`(sum)/(count)`

Here mean = 113, then

`(101+119+104+111+109+x)/(6)` = 113

`(544+x)/(6)` = 113 ( multiply both sides by 6 )

544 + x = 678 ( subtract 544 from both sides )

x = 134
