Step-by-step explanation
(A) The range of a set of numbers is the difference between the largest number and the smallest number.
Therefore, the range of the wages is:
![\begin{gathered} \pounds525-\pounds140 \\ \pounds385 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/hgfn3gk6jhd3zgo05kn5lhemmxt6aad3zo.png)
(B) The mean wage can be found by summing all the wages and dividing by the total number of wages given.
Therefore, the mean wage is:
![\begin{gathered} Mean=(\pounds(245+140+525+163+195+174+140))/(7) \\ Mean=(\pounds1582)/(7) \\ Mean=\pounds226 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/oe14dgcy73152xm4m2w5epd9oilipwf9vd.png)
