Use technology (such as a binomial calculator) to find the probabilities shown below. Then determine if the events are unusual. Explain your reasoning. Sixty-eight percent of pet owners say they consider their pet to be their best friend. You randomly select 12 pet owners and ask them if they consider their pet to be their best friend. Find the probability that the number who say their pet is their best friend is (a) exactly nine, (b) at least eight, and...
Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities. The mean number of births per minute in a country in a recent year was about three. Find the probability that the number of births in any given minute is (a) exactly five, (b) at least five, and (c) more than five. (a) P(exactly five)-...
Decide whether you can use the normal distribution to approximate the binomial distribution. If you can use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot explain why and use the binomial distribution to find the indicated probabilities A survey of adults found that 8% say their favorite sport is auto racing. You randomly select 600 adults and ask them to name their favorite sport. Complete parts (a) through (d). Determine whether a normal...
