Question

Data is arrange i. Ascending order for what vue is the media. Of the data 5,4,7-2a,6a,-5,2,1 equal to 11

Answer 1

The value of a is $\frac{11}{6}$

Step-by-step explanation:

as, the data is arranged in ascending order

5,4,7-2a,6a,-5,2,1

total number of observations = 7

i.e odd  number of observations  n= 7

median given = 11

if number of observations is odd then

median = $(\frac{n+1}{2})^t^h$ term

11 = $(\frac{7+1}{2})^t^h term$

11 = $(\frac{8}{2})^t^h term$

11 = 4th term

4 th term in data = 6a

then 6a = 11

a = $\frac{11}{6}$

hence ,

The value of a is $\frac{11}{6}$
