Question

The mean of 1 7 5 3 4 and 4 is m.the observations 3 2 4 2 3 3 and p have mean m-1 and median q.find p and q

Answer 1

☆ranshsangwan☆☆


m = 1+7+5+3+4+4/6

m = 24/6
m=4

second mean = m-1

=3+2+4+2+3+3+p/7 = 4-1
=17+p/7=3
=17+p = 21
p=4

Median

Asc. Order - 2,2,3,3,3,4,4

median for odd = (x+1)/2
x=7

(8/2) 4th observation

= 3 

p=4
q=3

 

Answer 2

m = 1+7+5+3+4+4/6

m = 24/6
m=4

second mean = m-1

=3+2+4+2+3+3+p/7 = 4-1
=17+p/7=3
=17+p = 21
p=4

Median

Asc. Order - 2,2,3,3,3,4,4

median for odd = (x+1)/2
x=7

(8/2) 4th observation

= 3 

p=4
q=3

I hope it helps u dear........
