Approximately 12% of all people are left-handed. Consider 14 randomly selected people.

c) Explain why this is a binomial experiment. Check all that apply.

• There are more than two outcomes for each person
• Whether or not one randomly selected person is left-handed will affect whether or not another randomly selected person is left-handed
• Whether or not one randomly selected person is left-handed will not affect whether or not another randomly selected person is left-handed
• There is not a fixed number of people
• p = 12% remains constant from one randomly selected person to another
• There are a fixed number of people, 14
• There are only two outcomes for each person

Find the probability, to 4 decimal places:

It is possible when rounded that a probability is 0.0000 d) exactly none are left-handed. e) exactly 10 are left-handed. f) at least 5 are left-handed. g) at most 7 are left-handed. h) at least 8 are left-handed. i) Is 8 an unusually high number of people that are left-handed in a sample of 14 people?
