Answer 1

The mean weight of the 10 boys is 42 kg.

Step-by-step explanation:

The mean of n values is:

$\bar x=\frac{1}{n}\sum x$

Given:

The data set of the weight of 10 boys is:

S = {44, 36, 39, 42, 53, 41, 50, 36, 43, 36}

Compute the mean weight as follows:

$\bar x=\frac{1}{10}[44+36+39+42+53+41+50+36+43+36]=\frac{420}{10}=42$

Thus, the mean weight of the 10 boys is 42 kg.
