Step-by-step explanation:

from the question:R=x^2/y

where x=3.8*10^5

y=5.9*10^4

it then mean

R=(3.8*10^5)^2/5.9*10^4

=144400000000/59000

Suppose that .06 of each of two populations possess a given characteristic. Samples of size 400 are randomly drawn from each pop
omeli [17]

Answer:

The correct answer to the following question will be "0.0367".

Step-by-step explanation:

The given values are:

p1=p2=0.06

q1=q2=1-p1=0.94

n1=n2=400

As we know,

E(p1-p2)=p1-p2=0\\

SE(p1-p2)=\sqrt{\frac{p1q1}{n1}+\frac{p2q2}{n2}}

On putting the given values in the above expression, we get

                   = \sqrt{p1q1(\frac{1}{400}+\frac{1}{400})}

                   =0.0168

Now, consider

P(p1-p2>0.03)=P[\frac{(p1-p2)-E(p1-p2)}{SE(p1-p2)}>\frac{0.03-0}{0.0168}]

                            =P(Z>1.7857)

                            =P(Z>1-79)

                            =0.036727

Therefore, "0.0367" is the right answer.
