What is the probability that the entire batch unnecessarily has to be tested if in fact 95% of its laptops conform to specifications?
Assignment What are the 4 characteristics of a binomial experiment? Can we use a binomial distribution to model this process? What is the probability that the entire batch unnecessarily has to be tested if in fact 95% of its laptops conform to specifications? (Hint: Use Excels =BINOMDIST() function to find the probability) What is the […]
Based on the relevant binomial distribution, answer the following questions about X, the number of American workers who say job stress caused frequent health problems: What is the probability that X is at least 15?
Binomial distribution A survey conducted for the Northwestern National Life Insurance Company revealed that 70% of American workers say job stress caused frequent health problems. Suppose a random sample of 20 American workers is selected. Based on the relevant binomial distribution, answer the following questions about X, the number of American workers who say job […]
