In order to estimate f. the true fraction of smokers in a large population, Alvin selects n people at random. His estimator Mn is obtained by dividing Sn, the number of smokers in his sample, by n, i. e. Mn = Sn/n. Alvin Chooses the sample size n to be the smallest possible number for which the Chebyshev inequality yields a guarantee that,

P(|Mn - f| >= epsilon) <= Delta,

where epsilon and dela are some prespecified tolerances. Determine how the value of n recomended by the Chevyshev inequality changes in the following cases.

A) The value of epsilon is reduced to half its original value.

B) The probability delta is reduced to half its original value.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

i think the answer is d im not sure
