Binomial Distribution Practice Problems: 1. A four-year study of various brands of bottled water found that 30% of bottled water is just tap water packaged in a bottle. Consider a sample of four bottled-water brands, and let x equal the water packaged in a bottle. Consider a sample of four bottled-water brands, and let x equal the number of these brands that use tap water. Complete parts a) through c). a). Find P(x=0) b). Find P(x=3) c). Find P(x≤1) 2. Suppose that 38% of all births in a certain region take place by Caesarian section each year. a). In a random sample of 1,000 births, how many, on average(mean), will take place by Caesarian section? b). What is the standard deviation of the number of Caesarian section births in a sample of 1,000 births? 3. A comprehensive report called the Statistical report on the Health of Canadians was produced in 1999. It was reported that 42% of Canadians, 12 years of age or older, had their most recent eye examination within the previous year. If a random sample of 8 Canadians in this age group were selected, find the probability that the selected individuals would have had their most recent eye examinations: a). at least one b). at most 2 c). exactly 3 d). all of them
