Question

The observations of an ungrouped data are x1, x2 and 2x1 and x1 < x2 < 2x1. If the mean and median of the data are each equal to 6. Find the observations of the data

Answer 1

Step-by-step explanation:

hey dude the answer will be same like this process

Answer 2

Answer:

The observations of the data 3.

Step-by-step explanation:

GIVEN:

      The observations of an ungrouped data are

                         $X_{1} ,X_{2} ,2X_{1}, AND,X_{1} < X_{2} < 2X_{1}$ it is ascending order of the following.

 The mean and median of the data are each equal to 6.

    WE know that Mean= sum of observation / number of observation

        n=3,  Which is a odd.

        Median=  $(\frac{(n+1)}{2} )$th observation.

     Given that median of scores .

              $2x_{1} =6\\x_{1} =\frac{6}{2} \\=3$

The observations of the data is 3
