In 2015 the CDC reported that 15.1% of adults in the United States were smokers. You suspect that the proportion of smokers has decreased since then. You take a random sample of 200 adults and found that 10.3% were smokers. You're no hypothesis is P equals 0.151. What is the alternative hypothesis?

(c, 0) i might be wrong so don't put full faith on my answer

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
