Pla its very important pls solve​

Answer 1

Answer:

Let us arrange the data in ascending order

32,35,36,37,38,38,38,40,42,43,43,43,45,47,50.

i) Mode = 38 and 43 as they occured the maximum number of times

Median = \left(\frac{n+1}{2}\right)^{th}\(2n+1)th 

n = 15

\frac{15\ +\ 1}{2}215 + 1

= \frac{16}{2\ }\ =\ 8th\ term2 16 = 8th term

8th term = 40

Thus, mode of the data is 38 and 43

Median = 40

ii) Yes, the given data has two modes.
