What is variance and the standard deviation of the interruptions? Historical data indicates that only 20% of cable customers are willing to switch companies. If a binomial process is assumed, then in a sample of 20 cable customers, what is the probability that exactly 2 customers would be willing to switch their cable? Historical data indicates that only 20% of cable customers are willing to switch companies.
