Answer: 0.68
Step-by-step explanation:
given data:
ABC market share = 30%
number of customers surveyed = 800
probability that more than 32% prefers ABC
Solution:
32% of 800
= 256 persons
p ( x ≥ 256 )
= 1 - ( 256/800 )
= 1 - 0.32
= 0.68
the probabiliy that more than 32% of those who carried out the survey would prefer ABC brand is 0.68.
Keeping in mind that 120 days is not even a year, since there are 365 days in a year, exluding leap-years, then 120 days is really 120/365 year.
