Which of the following situations can use
the binomial probability distribution?
a. The number of defects per mile of highway.
b. The number of customers handled per teller per day at a local
bank.
c. A sampling of 100 parts to determine whether or not they meet
specifications.
d. The probability of earning a grade of between 80% - 90%
on this exam.
The difference between the binomial and the Poisson
distributions is that:
a. the binomial involves "x" successes in "n" trials, while the
Poisson involves "x" successes over time or space.
b. the binomial is a discrete probability distribution, while
the Poisson is a continuous probability distribution.
c. the binomial is a probability distribution, while the Poisson
is a frequency distribution.
d. the Poisson is a discrete probability distribution, while the
binomial is a continuous probability distribution.
The probability is 60% that a person earning more than $40,000
per year owns their own home. If ten people are selected
at random, what is the probability that at least
seven will own a home? (Hint: Think of the
"characteristics" of the probability situation, then use the
appropriate table.)
a. 0.382
b. 0.0006
c. 0.618
d. 0.215
The correct table to use when answering the previous question
is the:
a. Poisson distribution table.
b. binomial distribution table.
c. uniform distribution table.
d. normal distribution table.
