Question

If the mean of observations 22,20,19,16, x is 19, Find "X"

Answer 1

Step-by-step explanation:

Mean=sum of the observation/no of the observation

Hence,

19=20+22+19+16+x÷5

19=77+x÷5

19×5=77+x

95-77=x

18=x

Answer 2

Answer:

X=20

Step-by-step explanation:

MEAN=sum of observations/no of observations

        =22+20+19+16+x/5=19

      =75+X=19*5

      =75+X=95

         X=95-75

           X=20
