The prime factorization is 2×5
The null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.
First, let us understand the Null and Alternative hypotheses:
The null hypothesis is simply to predict that there is no effect of the relationship between the variables.
The alternative hypothesis is to state the research prediction of a relationship or effect. In this case, the newsletter publisher believes that below 68% of their readers own a Rolls Royce.
The null hypothesis is that the proportion of readers who own a Rolls Royce is equal to 0.68.
Null hypotheses = H₀: p = 0.68
The alternate hypothesis is that the proportion of readers who own a Rolls Royce is below 0.68.
Alternate hypotheses = H₁: p < 0.68.
Thus, the null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.

The answer I got was 15/75
Multiplicity is hoa many times it repeats
example
if you have roots, r1 multiplicity 2 and r2 multiliicty 3 the factors are
f(x)=(x-r1)^2(x-r2)^3
so
multiplicty 2 at x=4
multilicty 1 at x=-2
(x-4)^2(x-(-2))^1=
(x-4)^2(x+2))
expand
x^3-6x^2+32
remember
for roots, r1 and r2
(x-r1)(x-r2)
the roots don't change if you multiply whold thing by a unless a=0
so
the yint is where x=0
so the yint now is 32
32 times what=-9.6?
divide both sides by 32
what=-0.3
the polynomial is
p(x)=-0.3(x-4)²(x+2)
expanded is
p(x)=-0.3x³+1.8x²-9.6
