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 =
=
When 894 is included in the data, the mean becomes
So, the mean increases.
<MAX = 93
Since <MAX is technically <1 + <5, we know that <1 is 28 and <5 is 65. We can add both of these angles up to solve for <MAX, which is 28 + 65 = 93.
