You may need to use the appropriate appendix table or technology to answer this question. A binomial probability distribution has p = 0.20 and n = 100. (a) What are the mean and standard deviation? mean standard deviation (b) Is this situation one in which binomial probabilities can be approximated by the normal probability distribution? Explain. No, because np > 5 and n(1 - p) > 5. Yes, because n > 30. No, because np < 5 and n(1-p) <...
You may need to use the appropriate appendix table or technology to answer this question. According to a 2018 survey by Bankrate.com, 20% of adults in the United States save nothing for retirement (CNBC website). Suppose that 15 adults in the United States are selected randomly. (a) Is the selection of the 15 adults a binomial experiment? Explain. The selection --- is or is not ----- a binomial experiment because the adults are selected ------ by choice or randomly -----, p --- changes...
