Question

The following table of grouped data represents the weight (in pounds) of 100 computer towers. Calculate the mean weight for a computer. Weight (pounds) Number of Computers [3 - 5) 8 [5 - 7) 25 [7 - 9) 45 [9 - 11) 18 [11 - 13) 4​

Answer 1

Step-by-step explanation:

The following table of grouped data represents the weight (in pounds) of 100 computer towers. Calculate the mean weight for a computer. Weight (pounds) Number of Computers [3 - 5) 8 [5 - 7) 25 [7 - 9) 45 [9 - 11) 18 [11 - 13) 4

(C)

Answer 2

Given,

Weight (pounds) Number of Computers [3 - 5) 8 [5 - 7) 25 [7 - 9) 45 [9 - 11) 18 [11 - 13) 4​

Solution,

Refer to the table.

Therefore, the mean is

$\[\begin{array}{l} \Rightarrow \frac{{\sum {fx} }}{{\sum f }}\\ \Rightarrow \frac{{770}}{{100}}\\ \Rightarrow 7.7\end{array}\]$

Hence, the mean is $\[7.7\]$.
