Answer:
The right options are C and D.
Step-by-step explanation:
One test refers to the claim that there is bias in the acceptance rate based on gender. In this case, the alternative hypothesis would claim that there is a significant difference in proportions in acceptance rate for both genders. The null hypothesis failed to be rejected, so the P-value has to be more than the significance level.
<em>C. One set of hypotheses concerns whether acceptance rates are lower (the alternative) or equivalent (the null) when the author or editor is female. The p-value for that test was apparently above 0.05.</em>
The other test is referred to the preference in gender to choose reviewers. The alternative hypothesis claim that female editors used female reviewers more often than did male editors. This has a P-value<0.001.
<em>D. One set of hypotheses concerns whether female editors chose females to review the papers less often than the alternative) or the same amount as the null) did male editors. The p-value for that test was reported to be less than 0.001.</em>

Answer:
a. -216, 0 real roots
Step-by-step explanation:
The discriminant of ...
ax² + bx + c = 0
is ...
d = b² -4ac
When we put your equation into the standard form shown above, we get ...
7n² +8n +10 = 0
Then we can identify a=7, b=8, c=10. The discriminant is then ...
d = 8² - 4·7·10 = 64 -280 = -216
___
The interpretation of the discriminant is ...
- < 0; no real roots (2 complex roots)
- = 0; one real root (multiplicity 2)
- > 0; 2 real roots
Your discriminant is -216, so there are 0 real roots.
Answer:
y = -5.5
Step-by-step explanation:
The only lines that have a slope of 0 are horizontal lines. Horizontal lines are always in the form y = c where c is a constant. Basically, on a horizontal line, no matter what x is, y will always be the constant c. Therefore, the x coordinate of our given point does not matter and we only have to look a the y-coordinate, which is -5.5. Therefore, the equation is y = -5.5.
