Answer:

B. $ 3094.01

Step-by-step explanation:

Given observations are,

$2894.21, $1777.15, $2144.77, $4096.37, $4046.29, $1786.37, $3296.69, $4086.27, $2784.22

Number of observations = 10,

Sum of the observations = 2894.21+1777.15+2144.77+4096.37+4046.29+1786.37+3296.69+4086.27+2784.22+4027.79 = 30940.13,

Hence,

$Mean = \frac{\text{Sum of observations}}{\text{Number of observation}}$

$=\frac{30940.13}{10}$

$=3094.013$

$\approx 3094.01$

Option 'B' is correct.
