PTake a Test Secure : ". Test:Ch 4 Test Time Limit: 02:00:00 Submit Test This Question: 1 pt 14 of 14 (12 complete) This Test: 14 pts possible 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 10 pet owners and ask them if they consider their pet to be their best friend. Find the probability that the number who say thei pet is their best friend is (a) exactly eight, (b) at least six, and (c) at most three. (a) P(exactly eight)Round to four decimal places as needed.) b) Plat least six)-(Round to four decimal places as needed.) (c) Plat most three- ] (Round to four decimal places as needed.) Which of the events are unusual? Select all that apply A. The event in part (a) is unusual because it is highly unlikely to occur. B. The event in part (b) is unusual because it is highly unlikely to occur C. The event in part (c) unusual because it is highly unlikely to occur D. None of the events are unusual because none of them are highly unlikely to occur Click to select your answer(s)Explanation / Answer
From the binomial probabilities calculator, the corresponding probabilities will be:
a) 0.2107
b) 0.8133
c) 0.0155
