Answer:
C- There is a 3.8% chance that natural sampling variation could produce poll results at least as far below 54% as these if there is really no change in public opinion.
Step-by-step explanation:
The p-value indicates the probability that the test statistic occurs, given that the parameters of the null hypothesis are true.
The smallest the p-value, the less likely is the sample statistic obtained. If this p-value is below a threshold, called "level of significance", it can be claimed that the null hypothesis is wrong.
In this case, we can not say anything about the probability of success of the ad campaign or the quality of the poll, because we have no information about it.
Answer:

0.125= 1/8, and 1/8 is between 1/10 and 1/7
From the given f(x) and g(x), the value of (g-f)(2)=1
Given :
The functions are
Lets evaluate (g-f)(2)
To find out g(2), replace 2 for x in g(x) and then replace 2 for x in f(x)
Now we find g(2)-f(2)

Answer:
6-11i
Step-by-step explanation:
(2 + 7i) - (6 + 8i) + (10 - 10i)

Combine like terms
2-6 +10 +7i-8i-10i
6 -11i
