If 18 people out of 8,400 people responded to a sales offer, how many of the 8,400 people read the offer but did not respond? I am seeking a probability statistic such as used in a "coin toss", not subtraction (i.e. not 8,382 as the answer). Thank you
i think that you are asking about the proportion of people who read the offer but not respond which is equal to - 1-prob. of people who respond.
now prob. of people who respond =no. of people who respond/total no. of people =18/8400=0.0021
therefore required probability or proportion of people who not respond =1-0.0021 = 0.9979

When doing polling, for instance to figure out how popular a given candidate is, a common trick is to just ask N many people whether they support that candidate, and take the support to be the faction of people who say yes: if 70 people support the candidate out of 100 asked, we estimate the support at 70% or 0.7. Suppose that the probability a person supports a candidate is p, which you do not know. Let pˆN be the...

CASE STUDY 9.3 Integrated Marketing Strategy Many people who might benefit from hearing aids do not wear them.

Among adults aged 18 years or older with impaired hearing, 78 percent do not own a hearing aid. As the US population ages, the need for hearing assistance will become nearly universal—but even today among the hearing impaired who are aged 65 years or older, 61...
