We know that
• There are 14 employees with a salary of $21,400.
,
• 12 employees with a salary of $23,700.
,
• 17 employees with a salary of $26,100.
,
• 2 employees with a salary of $31,700.
,
• 5 employees with a salary of $39,700.
,
• 1 employee with a salary of $148,900.
To find the mean, we have to sum all the salaries first.
![21400+23700+26100+31700+39700+148900=291500](https://img.qammunity.org/2023/formulas/mathematics/college/p54jklct625bkex3mesd9szuv7mx7eosi0.png)
Then, we divide the sum by the total number of employees.
![\bar{x}=(291,500)/(14+12+17+2+5+1)=(291,500)/(51)=5,715.67](https://img.qammunity.org/2023/formulas/mathematics/college/s4qkvvbbee2lt1grfzztnaiuveo6sr9n8r.png)
Hence, the mean is $5,715.67, approximately.
