Answer 2

We have these values


25, 25, 25
26, 26, 26, 26, 26, 26
27, 27, 27, 27
28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28
29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29, 29
30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30
31, 31, 31, 31, 31, 31, 31, 31, 31, 31
32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32
33, 33, 33, 33, 33, 33, 33
34, 34
35, 35
36


Let's add them up


25+25+25+26+26+26+26+26+26+27+27+27+27+28+28+28+28+28+28+28+28+28+28+28+28+28+28+28+29+29+29+29+29+29+29+29+29+29+29+29+29+29+29+29+29+29+29+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+31+31+31+31+31+31+31+31+31+31+32+32+32+32+32+32+32+32+32+32+32+32+32+33+33+33+33+33+33+33+34+34+35+35+36 = 2,981


Then divide by 100 since there are 100 values. So,


2,981/100 = 29.81


Meaning that
\[\LARGE \bar{x} = 29.81\]
which rounds to `29.8`
