Answer 1

Step-by-step explanation:

aranging them in an order :,23,23,23,23,24,24,24,25,26,27,27,28,28,28,29,30

n=16 which is an even number

so maiden will be

$\frac{ \frac{n}{2}th \: value + \frac{n}{2} + 1)th \: value }{2}$

=8th+9th value/2

=25+26/2=25.5

maiden is 25.5

the total sum of these values is 412 (calculator)

mean=total sum/n

=412/16=25.75

mean is 25.75

as 23 has come most frequently

so the mood is 23

it would be your humble consideration to mark me as the brainliest.
