$ blank

Explanation:

Step1: Calculate total salary

Multiply each salary by its frequency and sum them:
\(23000\times4 + 27000\times3 + 30000\times2 + 45000\times1\)
\(= 92000 + 81000 + 60000 + 45000\)
\(= 278000\)

Step2: Calculate total number of employees

Sum the frequencies: \(4 + 3 + 2 + 1 = 10\)

Step3: Calculate the mean

Divide total salary by total employees: \(\frac{278000}{10} = 27800\)

Answer:

\(27800\)
