The agent will receive 5% of the selling price of each home as a commission
$\$201,900\times5\%=10095\\\$205,200\times5\%=10260\\ \$195,800\times5\%=9790\\ \$210,300\times5\%=10515\\ \$199,900\times5\%=9995\\ \$215,500 \times5\%=10775\\ \$192,100\times5\%=9605$
The new data set is $9605;9790;9995;10095;10260;10515;10775$
The mean is $\bar x=\frac{9605+9790+9995+10095+10260+10515+10775}{7}\approx10147.86$
The median is $10095$
There is no mode.
The range is $10775-9605=1170$
The standard deviation is $\sigma=375.99$
