Question

the hourly wages of a sample of 34 employees of a clothing company are summarized in the table below.

number of employees	hourly wage (in dollars)
17	8.00
9	9.75

find the mean hourly wage of these 34 employees. round your answer to at least two decimal places.

Explanation:

Step1: Calculate total wage for each group

For the first group: $8\times6.25 = 50$
For the second group: $17\times8.00=136$
For the third group: $9\times9.75 = 87.75$

Step2: Calculate the sum of total wages

$50 + 136+87.75=273.75$

Step3: Calculate the mean

The mean $\bar{x}=\frac{273.75}{34}\approx8.05$

Answer:

$8.05$
