Question

4. The following observations have been
arrenged in
ascending order. If the median of the data is
47.5 find the valu of x .17, 21,23, 29, 39, 40, x
50,51, 54, 59, 67, 91,93​

Answer 1

Answer:

n = 14

Median:

$mean \: of \: {(\frac{n }{2}) }^{th } term \: \: \: \: and \: \: \: \: { (\frac{n }{2} + 1)}^{th} term$

$= > { (\frac{n}{2} )}^{th} \: term \: = { (\frac{14}{2}) }^{th} term = {7}^{th} term \: = x$

$= > { (\frac{n}{2} + 1) }^{th } term = { (\frac{14}{2} + 1) }^{th} term = {7 + 1}^{th} term = {8}^{th} term = 50$

$= > \frac{x + 50}{2} = 47.5$

$= > x + 50 = 95$

$= > x = 95 - 50 = 45$

Hope this answer helps you ^_^ !
