Answer 1

Answer: (D)

$36.47$

The data numbers are: $34,43,29,51,36,41,38,35,34,36,34,38,40,36,35,35,34,35,36,34,38,38,35,36,34,38,36,34,35,36$
Mean = $\frac{\text{Sum}}{\text{Total Numbers}}$
Sum of Numbers $=34+43+29+51+36+41+38+35+34+36+34+38+40+36+35+35$

$+34+35+36+34+38+38+35+36+34+38+36+34+35+36$
Sum $=1094$
Total Numbers $=30$
Mean $=\frac{1094}{30}$
Mean $=36.47$
