Question

5. Mean of variable x is 9. What is the mean of the variable y=x+4?
6. Find the median of 42,28,28,57,31,23,50,34,32,37
7. Mention the amnirical forn​

Answer 1

median= 33

If my answer is correct do tell me in the comment section below

Answer 2

Step-by-step explanation:

5. x=9

y=x+4 ...................A

put value of x in eq. A

y=9+4

y=13

6. first arrange them in ascending order

now, total no. of outcomes =10 [hence it is even]

now, median is equal to n/2

where, n is total no. of observation

in ascending order,

23,28,28,31,32,34,37,42,50,57

now, n=10

so median =[n/2]th term

=[10/2]th term

=[5]th term

now, check the 5th term in the arrangement of outcomes.

so, median = 32
