Answer 2

Answer:

median of the given data is 35

Step-by-step explanation:

x           f           c.f

0-10      6           6

10-20    9          15

20-30   14         29

30-40    12         41

50-60    19        60

60-70     10       70

Here, $\frac{N}{2} = \frac{70}{2} = 35$

Cumulative frequency just greater than 35 is 41

Corresponding class is 30-40

Thus, median class is 30-40

$median = l+ \frac{h}{f}(\frac{N}{2} -C)$

$l = 30, \ h=10, \ f=12, \ C = 29$

Median = $30+ \frac{10}{12}(35-29)$

             = $30+\frac{10}{12} (6)$

             = 30+5 = 35

Hence, median of the given data is 35
