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,
[tex]Mean = \frac{\text{Sum of observations}}{\text{Number of observation}}[/tex]
[tex]=\frac{30940.13}{10}[/tex]
[tex]=3094.013[/tex]
[tex]\approx 3094.01[/tex]
Option 'B' is correct.
