Question

The weight of students are: 45kg, 25kg, 82kg, 35kg, 55kg, 60kg, 32kg, 37,kg, 80kg, 21kg. Find the range and arithmetic means for the weights of the students

Answer 1

$\: \: \: \: \: \: \: \: \red{ \huge \frak{Hola! \: Mate}}$$\rightarrow\tiny \bf{mean = \frac{the \: sum \: of\: total \: observation}{the \: \:numbers \: of \: observation } } \\ \\ \rightarrow \: \tiny\frac{45 + 25 + 82 + 35 + 55 + 60 + 32 + 37 + 80 + 21}{10} \\ \\ \rightarrow \: \frac{472}{10} = 47.2}\\ \\ the\: range\: is\: between \:80-21.$

Answer 2

$<b>HELLO !$

GIVEN ÷

WEIGHT OF STUDENTS ARE

45,25,82,35,55,60,32,37,80,21
============================
ARITHMETIC MEANS=TOTAl SUM OF NO.÷TOTAL NO.OF STUDENTS
===============================
=45+25+82+35+55+60+32+37+80+21/10

=472/10

=47.2

SO, ARITHMETIC IS 47.2
======================
RANGE IS THE HIGHEST NO.-SMALLEST NO.

SO HIGHEST NO.IS=82
====================
SMALLEST NO.=82-21

=61
====================
SO,RANGE IS. 61
