Question 65

7.8
Topic 8: The Binomial Distribution
63. Suppose X follows a Binomial distribution. Is X continuous or discrete? Explain in your own
words.
64. A particular test has a 72% pass rate. A teacher decides to grade tests until 15 people have
passed before stopping for a break. Let X = the number of tests graded before taking a break.
Determine if X is binomial by stating and checking all four requirements. If X is binomial,
summarize the distribution of X in shorthand notation.
65. Suppose 22% of students at a certain university are out of state students. A professor takes a
random sample of 50 students. Let X = the number of out of state students in the sample.
Determine if X is binomial by stating and checking all four requirements. If X is binomial,
summarize the distribution of X in shorthand notation.
66. Sickle-cell disease is a group of inherited blood disorders that can cause pain, anemia, swelling,
infections, and stroke. It affects about 0.3% of all Americans. Let X = the number of children
in a family of 4 that have sickle cell disease. Determine if X is binomial by stating and checking
all four requirements. If X is binomial, summarize the distribution of X in shorthand notation.
67. About 10% of the general population is left handed. However, about 25% of baseball players are
left handed.
(a) Let X
population. State n and p. Find the expected number of left handers and the standard
the number of left handers in a random sample of 25 people from the general
deviation.
(b) Let X = the number of left handers in a random sample of 25 baseball players. State n
and p. Find the expected number of left handers and the standard deviation.
68. Suppose 22% of students at a certain university are out of state students. A professor takes a
random sample of 50 students. Let X the number of out of state students in the sample.
(a) How many students are expected to be out of state? By how much does this vary?
(b) What is the probability that 10 will be out of state?
(c) What is the probability that 10 or fewer will be out of state?
(d) What is the probability that fewer than 10 will be out of state?
69. About 10% of the general population is left handed. However, about 25% of baseball players are
left handed. Suppose we take a random sample of 30 baseball players and let X = the number
of left handed players in the sample.
(a) What is the probability that at most 8 are left handed?
(b) What is the probability that 8 are left handed?
(c) What is the probability that more than 12 are left handed?
(d) What is the probability that at least 12 are left handed?
