Answer:

£16,833.33

Explanation:

The computation of mean income is shown below:-

Mean income = Total sum of salaries ÷ Number of workers

= £9,500 + £25,000 + £13,250 + £72,000 + £12,750 + £29,500 + £11,000

= £173,000 ÷ 7

= £24,714.29

Now, the Mean income excluding Deva's salary:

Mean income = Mean income

= Total sum of salaries excluding Deva salary ÷ Number of workers

= (£9,500 + £25,000 + £13,250 + £12,750 + £29,500 + £11,000) ÷ 6

= £101,000 ÷ 6

= £16,833.33

We simply applied the above formulas
