It has been hypothesized that silicone breast implants cause illness. In one study it was found that women with implants were mo

ZanzabumX [31]

Answer:

This study casts doubts as the hypothesis does not support the women who are smokers, drinkers or use dyes besides the difference of breasts implants.

Step-by-step explanation:

This study casts doubts as the hypothesis does not support the women who are smokers, drinkers or use dyes.

If the null and alternate hypothesis are formulated as

H0 : silicone breasts implants cause illness in smokers, drinkers and hair dyed people

against the claim

Ha: silicone breasts implants do not cause illness in smokers, drinkers and hair dyed people

then there would be no doubt .

But as the null and alternate hypothesis are

H0: silicone breast implants cause illness in women

against the claim

Ha: silicone breast implants do not cause illness in women

This suggests that both categories of women have same characteristics.

But actually both categories do not have same characteristics. The breast implant women also , smoke, drin and dye hair.

So when the characteristics are changed the illness maybe caused by some other characteristics.

A consumer organization estimates that over a 1-year period 16% of cars will need to be repaired once, 9% will need repairs

Mice21 [21]

Answer:

A consumer organization estimates that over a 1-year period 16% of cars will need to be repaired once, 9% will need repairs twice, and 3% will require three or more repairs..

We have the cars that do not need repair = $100-(16+9+3)=72$ %

(16+9+3=28% cars need repair of some sort)

What is the probability that :

a) neither will need repair?

=> $0.72\times0.72=0.5184$

b) both will need repair?

=> $0.28\times0.28=0.0784$

c) at least one car will need repair?

=> $1-(0.72\times0.72)$

=> $1-0.5184=0.4816$
