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 
<u><em>Step(ii):</em></u>-
Given margin of error = 2 % =0.02
The margin of error is determined by



√n = 25
squaring on both sides, we get
n = 625
You would plug the 2 into the place of the n. 50+100(2). the answer is 250.
