Answer 2

Average wage  = 31.465

Explanation:

Wage      mean wage       No. of Workers

0-10                  5                       10

10-20                15                     42

20-30               25                    58

30-40               35                     35

40-50               45                     44

50-60               55                     26

Total no. of workers $= 10 + 42 + 58 + 35 + 44 + 26 = 215$

Average wage $=$$\frac{{\displaystyle\sum_{}}(mean\;wage\ast no.\;of\;worker)}{{\displaystyle\sum_{}}no.\;of\;workers}$

Average wage $=$ $\frac{(5\ast10)+(15\ast42)+(25\ast58)+(35\ast35)+(45\ast44)+(55\ast26)}{10\;+\;42\;+\;58\;+\;35\;+\;44\;+\;26}$

$=\frac{6765}{215}$

$=31.465$
