Answer:

<u>X-18</u>

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 6-x-(-12)=0

Solve  :    -x+18 = 0

Subtract  18  from both sides of the equation : -x=-18

Multiply both sides of the equation by (-1) :  x = 18

Apple launches an ad campaign for iPhone 12. Managers want to know what is the % of social media mentions that have positive rea
Orlov [11]

Answer:

social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%

Sample size 'n' = 625

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given data Apple launches an ad campaign for iPhone 12

Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign

probability of positive reactions p = 1/2

Probability of negative reactions q = 1-p = 1/2

we know that \sqrt{p(1-p}\leq \frac{1}{2}

<u><em>Step(ii):</em></u>-

Given margin of error  = 2 % =0.02

The margin of error is determined by

          M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }

         0.02 = \frac{\frac{1}{2}  }{\sqrt{n} }

        \sqrt{n} =\frac{1}{2 X0.02}

        √n = 25

squaring on both sides, we get

       n = 625
