What is a potential benefit and potential negative impact of the work of the DNI?
ehidna [41]

The Director of National Intelligence’s work involves coordinating the many intelligence's agencies in charge of security and espionage in our country.

<u>Explanation:</u>

Some of these have had historically conflicting objectives (the DEA efforts against drug trafficking conflicted with the CIA strategy to finance counter communism movements) and the operate with high degree of secrecy.

On the positive side, their work protects the life and safety of Americans from unknown threats.

On the negative side, the secrecy they operate makes them difficult to be held accountable and they operate in the margins of people’s rights. There’s a trade off between Security and Liberty, and sometimes the threats to security do not seem to justify the cutback on liberties.

Alternative hypothesis: \mu >40000

Explanation:

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

On this case the Management try to proof that due to a new production process, the life expectancy of its tires has increased. So this needs to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.

Null hypothesis :\mu \leq 40000

Alternative hypothesis: \mu >40000

Other important thing is that on the alternative hypothesis we never can have the symbol equal.

Based on this the best option on this case is b.
