Question

the dot plot gives the weekly wage of the 16 employees of the tiptop company. from the table compute the mean weekly wage of the employees.
weekly wage of tiptop employees
each ● represents one employee

Explanation:

Step1: Calculate the sum of all wages

$$\begin{align*} &(355\times2)+(365\times5)+(375\times4)+(395\times1)+(405\times3)+(415\times1)\\ =&710 + 1825+1500 + 395+1215+415\\ =&710+1825 = 2535\\ &2535+1500=4035\\ &4035 + 395=4430\\ &4430+1215 = 5645\\ &5645+415=6060 \end{align*}$$

Step2: Calculate the mean

The total number of employees \(n = 16\). The mean formula is \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). So \(\bar{x}=\frac{6060}{16}=378.75\)

Answer:

\(378.75\)
