Answer:
Step-by-step explanation:
Let x be a random variable representing the number of U.S. adults who think that political correctness is a problem in America today. Since it is a binomial probability distribution, the probability if success, p = 78/100 = 0.78
The probability of failure, q = 1 - p = 1 - 0.78 = 0.22
Number of samples = 6
Mean = np = 6 × 0.78 = 4.7
Variance = npq = 6 × 0.78 × 0.22 = 1.0
Standard deviation = √variance = 1.0
Most samples of 6 adults would differ from the mean by no more than 1
