Answer:
623/2
Step-by-step explanation:
Answer:
a. 1.44
Step-by-step explanation:
We are interested in determining whether or not the proportion of the population in favor of Candidate A is significantly more than 40%.
At the null hypothesis, it is tested if the proportion is of at most 40%, that is:

At the alternative hypothesis, it is tested if the proportion is of more than 40%, that is:

The test statistic is:
In which X is the sample mean,
is the value tested at the null hypothesis,
is the standard deviation and n is the size of the sample.
0.4 is tested at the null hypothesis:
This means that 
A random sample of 200 people was taken. 90 of the people in the sample favored Candidate A.
This means that:

Value of the test statistic:



Thus the correct answer is given by option a.

Answer:
The answer is
y = 6x + 43
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = 6x + 1
Comparing with the general equation above
Slope = 6
Since the lines are parallel their slope are also the same
Slope of parallel line = 6
The equation of the line using point (-7,1) and slope 6 is
We have the final answer as
y = 6x + 43
