Question

Income tax rates for 7 state's (%). I will send image

Answer 1

Determine the mean for the income tax rate.

`\begin{gathered} \text{Mean}=(6+8+3+5+6+7+0)/(7) \\ =(35)/(7) \\ =5 \end{gathered}`

The mean is 5.

Arrange the tax rate from least to greatest.

`0,3,5,6,6,7,8`

There are odd number of tax rate so median term is (n+1)/2, which is equal to

`(7+1)/(2)=4`

The fourth term is 6. So median is 6.

The tax rate 6 occured twice in data. So mode of the data is 6.

The highest tax rate is 8 and lowest tax rate is 0.

Detrmine the range for the tax rate.

`\begin{gathered} \text{Range}=8-0 \\ =8 \end{gathered}`

Thus answers are;

Mean : 5

Median: 6

Mode: 6

Range: 8
