$36^oC$ and

$37^oC$ will represent

$36.5^oC.$

The class marks of a frequency distribution are given as follow 15,20,25,...
The class corresponding to the class mark 20 is

0%
$12.5-17.5$
0%
$17.5-22.5$
0%
$18.5-21.5$
0%
$19.5-20.5$

Explanation

Width=5

Class marks=20

$\therefore Lower\ limit=20-\dfrac{5}{2}$

$\Rightarrow \dfrac{40-5}{2}=\dfrac{35}{2}=17.5$

$Upper\ limit=20+\dfrac{5}{2}$

$\Rightarrow \dfrac{40+5}{2}=\dfrac{45}{2}=22.5$

Hence the class corresponding to the class mark 20 is

$17.5-22.5.$

Class mark of a particular class is 6.5 and class size is 3 then class interval is:

0%
$5-8$
0%
$6.5-9.5$
0%
$3.5-6.5$
0%
$4-7$

Explanation

Let the a be the lower limit of the class interval

Class size of the class interval =3

$\therefore$ Upper limit of the class interval

$=a+3$

Class mark=6.5

$\therefore \dfrac{a+a+3}{2}=6.5$

$\Rightarrow 2a+3=6,5\times 2$

$\Rightarrow 2a=13-3$

$\Rightarrow 2a=10\Rightarrow a=\dfrac{10}{2}=5$

$\therefore a+3=5+3=8$

Hence class interval=

$5-8$
