Do I have to do anything particular with the .02 probability of
a random state?
Produce a table like the following that lists counts for the
number of states visited by Person A and Person B:
Person B has visited
Person B has not visited
Total
Person A has visited
2
0
2
Person A has not visited
0

A. When a person is selected at random from a very large
population, the probability that the selected person has brown eyes
is 0.62. If 4 people are selected at random, find the following
probabilities :
1. they all have brown eyes
2. none of them have brown eyes
B. In a study of sandhill cranes, the distance traveled in one
day is normally distributed, with a mean of 267 kilometers and a

A crowd of people is in a room. One person from the room is
selected randomly. Suppose that we know that 1/5 of the people are
over six feet tall. 1/8 of the people have green eyes. The
probability that we select someone with either green eyes or who is
over six feet tall is given by P(T union G) = 0.25
a. Find the probability that the person selected has green eyes
and is taller than six feet.
b....

Market researchers selected a random sample of people from
region A and a random sample of people from region B. The
researchers asked the people in the samples whether they had tried
a new product. The difference between the sample proportions (B
minus A) of people in the regions who indicated they had tried the
new product was 0.15. Under the assumption that all conditions for
inference were met, a hypothesis test was conducted with the
alternative hypothesis being that...

The probability that a randomly chosen person is Rh-positive is
85%.
What is the probability that a randomly chosen person is
Rh-negative?
What is the probability the next 5 people tested are
Ph-positive?
What is the probability that out of the 5 people who have tested
at least one is Rh-negative?
If two people get tested, what is the probability that one is
Rh-positive and the other is Rh-Negative?

A jury pool has 15 people that are married and 22 people that are
not married, from which 12 jurors will be selected. Assuming that
each person is equally likely to be chosen and that the jury is
selected at random, find the probability that the jury consists of
the following. (Give answer as a fraction or a decimal out to at
least 4 places. If your answer is very small use scientific
notation out to 4 decimal places for...

Of all people in one population, 21% have high blood pressure
and 36% are overweight. In addition, 42% of people who are
overweight also have high blood pressure. Let H represent the event
that a person has high blood pressure, and O represent the event
that a person is overweight. In each part of this question, you
must first express each probability in terms of the events H and O
and justify any computation through the use of a formula....

A random sample of 58 randomly selected people were asked how
much they spend on their grocery bill each week. The mean was
$115.36 with a standard deviation of $16.6. Find a 95% confidence
interval for the true population mean amount spent on groceries
each week. Report the answer accurate to four decimal places.
