1960 $4,995

ruslelena [56]

Answer:

Average mean salary $=$26327.83$

Step-by-step explanation:

We have been given year and respective salaries in each year.

1960 $4,995

1970 $8,626

1980 $15,970

1990 $31,367

2000 $41,807

2010 $55,202

Now we nee do to determine the average mean salary for the six decades, 1960 – 2010.

So we just need to add all those six salaries and divide that sum by 6 to find the average mean salary.

Average mean salary $=\frac{(4995+8626+15970+31367+41807+55202)}{6}$

Average mean salary $=\frac{(157967)}{6}$

Average mean salary $=26327.83333333$

Hence final answer is approx:

Average mean salary $=$26327.83$
