Question

​% of U.S. adults think that political correctness is a problem in America today. You randomly select six U.S. adults and ask them whether they think that political correctness is a problem in America today. The random variable represents the number of U.S. adults who think that political correctness is a problem in America today. Answer the questions below. Find the mean of the binomial distribution (Round to the nearest tenth as needed) et Find the variance of the binomial distribution (Round to the nearest tenth as needed) e Find the standard deviation of the binomial distribution verl the ơrD(Round to the nearest tenth as needed) Interpret the results in the context of the real-life situation. Most samples of 6 adults would differ from the mean by no more than

Answer 1

Answer:

Explanation has been given below

Step-by-step explanation:

hope fully it may concern with 70% adults then

p = 0.77

randomly select = 6

then mean will be

mean = n * p = 6*0.77=4.62

To get variance np (1-p)

then putting values we get

np (1-p) = 4.62 *0.23 = 1.0626

taking square root we get

$\sqrt{1.0626}$

sd = 1.03

Most samples of 6 adults would differ from the mean by no more than 1 sd

mean is differ by no more than 2 sds .

In a real-life situation, it is expected that 4 or 5 of 6 to think it is a problem.

I would not expect 0, 1, or 2.
