-3(2m-1)-n

First we multiply -3 to the first term of the expression

---------- > ( -3*2m + (-3)*(-1) ) - n

---------- > ( -6m + 3 ) - n

-----------> -6m -n + 3

Then, we divide and multiply by -6, (the expression remains the same)


---- > (-6/-6)* (-6m -n + 3)

---- > -6*[m + (n/6) - 1/2]

The answer is -6*[m + (n/6) - 1/2]

Step-by-step explanation:

Given that television networks frequently run public opinion polls on issues of concern. One network conducted a scientific poll asking a question concerning the approval rating of the way President Obama was handling the Iraq War. At about the same time a second network ran an online poll using a very similar question.

Observed data is

Poll Scien Online total

approve 339 385 724

disapprove 780 573 1363

1119 958 2087

$H_0: Both scientific and online are consistent\\H_a: not consistent$

(Two tailed chi square test)

Let us find out expected and chi square

Expected = row total x column total/grand total

The cell count expected in the online poll for those who approve

= $\frac{724*968}{2087} \\=333.94$

chi square = 7.81

Hence option d is right.
