Answer:

The step 4 is not what he should have done. But the wrong is step 5, because if he added -2x both sides, it would give the following equation:

x-12=-4x+6

and not x-12=6

Note that in step 4 he should have added 2x and not -2x to both sides, but we still have the equality. The problem is that step 5 is totally wrong.

I don't know what answer is expected to this question, but I would mark step 5, because this is mathematically wrong.  

Solving the equation

3(x-4)=-4-2(x-5)

Using distribution

3x-12=-4-2x+10\\3x-12=-2+6

Add 2x both sides

3x-12+2x=-2x+6+2x

5x-12=6

Add 12 both sides

5x-12+12=6+12\\5x=18

Divide both sides by 5

$x=\frac{18}{5} $

Ghella [55]

Answer:

The correct answer is option (E)

Step-by-step explanation:

Solution to the question

Let us recall from given question that,

H0:p=0.80

Ha:p≠0.80 (which is the two tailed test)

For the p-value we have,

P-value: Let us assume that the null hypothesis is true, then the probability of observing the sample statistics or the  more extreme,

Therefore if p= 0.80, the probability of observing or detecting proportion of samples is of at least 0.84 or at most 0.76 is 0.273.
