Question

find the constant of variation and write the equation of variation pa1/q if p=9 and q=5​ please give the answer fast

Answer 1

Answer:

Given standard deviation =11

Sample size, n=10

Standard deviation (S.D)=

n

∑(x

i

−

x

ˉ

)

2

=11

Mean =

x

ˉ

New mean =

x

ˉ

−2 (as every item decreases by)

New standard deviation =

n

∑(x

i

−2)−(

x

ˉ

−2)

2

=

n

∑(x

i

−2−

x

ˉ

+2)

2

=

n

∑(x
