Answer:

67%

Test for 2 Independent means

Explanation:

Given that:

Average Female earning per week in sample = $346.98

Average Male earning per week in sample = $517.70

Female earning in percent of male earning :

(Female earning / male earning) × 100%

(346.98 / 517.70) * 100%

0.6702337 * 100%

67.02%

= 67%

Testing whether or not the difference in weekly earning by males and female can be conducted by testing the difference in sample means of both males and females by taking the two different samples as being independent.

Usually :

Null hypothesis : H0 : m1 - m2 = 0

Alternative hypothesis : H1 : m1 - m2 ≠ 0

Review 4: AIMS Science Practice
Zolol [24]

Answer:

  • <u><em>D. It has both good and bad effects, but we can't always predict what those are.</em></u>

<u><em></em></u>

Explanation:

Of course,  ethics mandates that the target of science and <em>new technology </em>should always pursue the good for humans; nevertheless, since time immemorial man has developed technology to make war. Thus, definetely, the first statement <em>"A It always does good for human"</em> is false.

Some other negative effects of <em>new technology</em>, like cars and nuclear power, have been harmful to the environment, but you cannot tell that this has always been so. Technology has also been developed to help the environment. For instance, panels to use solar energy do not harm the environment and seek to reduce fuel burning to help the environment. Thus, option <em>B, "It always ends up doing harm to the environment"</em> is false too.

Some of the damage that new technology can produce are not predicted both because the technology is new and because it may be used with different goals to those it was developed. This explains why option <em>C, It has many bad effects</em>, is false, and option <em>D, "It has both good and bad effects, but we can't always predict what those are", </em>is true.
