In a random sample of males, it was found that 25 write with their left hands and 210 do not. in a random sample of females, it was found that 64 write with their left hands and 468 do not. use a 0.05 significance level to test the claim that the rate of left-handedness among males is less than that among females. complete parts (a) through (c) below. a.? test the claim using a hypothesis test. consider the first sample to be the sample of males and the second sample to be the sample of females. what are the null and alternative hypotheses for the hypothesis test? a. h0: p1=p2 h1: p1> p2b. h0: p1? p2 h1: p1? p2c. h0: p1=p2 h1: p1? p2d. h0: p1=p2 h1: p1

step-by-step explanation:

no of data

divide by no of mode

cosine

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
