Answer 1

Step-by-step explanation:

of 5,10,15,20,25,30

\begin{gathered}mean = \frac{sum \: of \: given \: observations}{no \: of \: given \: observation} \\ = \frac{5 + 10 + 15 + 20 + 25 + 30 + 35}{7} \\ = \frac{140}{7} \\ = 20\end{gathered}

mean=

noofgivenobservation

sumofgivenobservations

=

7

5+10+15+20+25+30+35

=

7

140

=20

\begin{gathered}median = value \: of \: \frac{1}{2} .(n + 1)th \: observation \\ = \frac{1}{2} (7 + 1) \\ \frac{1}{2} \times 8 = 4th \: observation \\ median = 20\end{gathered}
