Determine the mean for the income tax rate.
[tex]\begin{gathered} \text{Mean}=\frac{6+8+3+5+6+7+0}{7} \\ =\frac{35}{7} \\ =5 \end{gathered}[/tex]
The mean is 5.
Arrange the tax rate from least to greatest.
[tex]0,3,5,6,6,7,8[/tex]
There are odd number of tax rate so median term is (n+1)/2, which is equal to
[tex]\frac{7+1}{2}=4[/tex]
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.
[tex]\begin{gathered} \text{Range}=8-0 \\ =8 \end{gathered}[/tex]
Thus answers are;
Mean : 5
Median: 6
Mode: 6
Range: 8
