Answer:

The mean increases.

Step-by-step explanation:

Given data set is :

34, 75, 26, 81, 65, 38, 49

Arranging in ascending order, we have

26, 34, 38, 49, 65, 75, 81

Mean = \frac{26+34+38+49+65+75+81 }{7}

= \frac{368}{7}=52.57

When 894 is included in the data, the mean becomes

\frac{368+894}{8}=157.75

So, the mean increases.
