Question

What's the weighted mean frequency for the following car sales? 2 sold at $25,090, 3 sold at $20,000, 1 sold at $21,475, and 1 sold at $39,638

Answer 1

23,724 is the answere to your questing

Answer 2

The value of weighted mean is $24470

Explanation:

Weighted mean
`\bar{x}` is given by

`\bar{x} =(w_1x_1+w_2x_2+w_3x_3+w_4x_4)/(w_1+w_2+w_3+w_4)`

In the given question

`w_1=2 ,x_1= \$25090`

`w_2=3 ,x_2= \$20000`

`w_3=1 ,x_3= \$21475`

`w_4=1 ,x_4= \$39638`

Therefore

`\bar{x} =\$[(2*25090+3*20000+1*21475+1*39638)/(2+3+1+1)]`

=>
`\bar{x} =\$24470`

Thus the value of weighted mean is $24470
