For a given level of significance, if the sample size is increased: the power of the test will increase we will have more responses to log and calculate it will skew the mean to the right it has no effect on the direct results

the power of the test will increase

Explanation:

In simple terms, Power relates to the likelihood that the null statement will be correctly denied. The change in sample size allows the experiment more adaptive and decreases the continuous distribution of the data. Then perhaps the null statement is more probable to be discarded if it is simply incorrect. It is why the strength of the analysis rises.

Thus, from the above we can conclude that the correct answer is first statement.

no

the purpose of the heading in the passage is to identify who is telling the story.

this excerpt is part of the book sugar changed the world (2010) written by marc aronson and marina budhos. as the book has been written by two people, the heading "marc" indicates that this specific excerpt is being narrated by aronson. in the fragment, marc describes his grandfather's story after hearing it from his cousin. however, there are other excerpts where budhos is the one that tells the story of her family.
