Pavlova-9 [17]

Answer:

Step-by-step explanation:

Given : The data below represents the number of T-shirts sold per week by a student who started his own online t-shirt business.

T-Shirt Sold per Week(x_i) Frequency(w_i)

         2                                                          1

4                                                          4

6                                                          7

8                                                          3

To find : The weighted mean of the number of t-shirts sold per week ?

Solution :

The formula of weighted mean is

\text{Weighted mean}=\frac{\sum (x_i\times w_i)}{\sum w_i}

Substituting the values in the formula,

\text{Weighted mean}=\frac{2(1)+4(4)+6(7)+8(3)}{1+4+7+3}

\text{Weighted mean}=\frac{2+16+42+24}{15}

\text{Weighted mean}=\frac{84}{15}

\text{Weighted mean}=5.6

Therefore, The weighted mean of the number of t-shirts sold per week is 5.6.
