- Use the information in the table to fill in the blanks in the
row and column totals.

- How many people (male and female) got married in the State?

- If a person that was married was randomly chosen, what is the probability that the person was a female less than 20 years old? Express your answer as a percent rounded to the nearest whole percent.

- If a person that was married was randomly chosen, what is the probability that the person was a male less than 20 years old? Express your answer as a percent rounded to the nearest whole percent.
- If a person that was married was randomly chosen, what is the probability that the person was between the ages of 25 and 34? Express your answer as a percent rounded to the nearest whole percent.

- Of the people over the age of 45 who got married, what percentage was female? What percentage was male? Express your answer as a percent rounded to the nearest whole percent.

- Given that a person married was less than twenty years old, what is the probability that the person was male?

- Given that a person married was female, what is the probability that the person was between the ages of 35 and 44?

- If a person that was married was randomly chosen, what is the probability that the person was over the age of 45 or female?

- If a person that was married was randomly chosen, what is the probability that the person is male and between the ages of 25 and 34?

- Describe two events, A and B, which are
*mutually exclusive*for the number of marriages in the State*.*Calculate the probability of each event, and the probability of A or B occurring.

- Go to the state of Michigan’s website (http://michigan.gov) and search on “Vital Statistics”. Here you will find several categories containing interesting statistics about the state of Michigan.

- Which statistic or statistics from the website do you find interesting? Explain why you find it interesting.
- What information or “story” do the statistics tell you? Write 2-3 paragraphs summarizing the statistics.
- Is there any information lacking that might make the statistic more meaningful? Why or why not?

**PART 2:**

There are data that give the relative frequency probabilities of various types of accidents (such as being killed by lightning, by a shark bite, or by falling airplane debris).

Choose two types of fatal accidents and research the relative frequency probabilities of each. Compare and discuss your findings. Were you surprised by the results? Why or why not? Your answers should be a minimum of three complete sentences. Be sure to include your references.

The mean triglyceride level for U.S. adults (ages 20 and
older) is 97 milligrams per deciliter. Assume the triglyceride
levels of U.S. adults who are at least 20 years old are normally
distributed, with a standard deviation of 25 milligrams per
deciliter. You randomly select a U.S. adult who is at least 20
years old. What is the probability that the person triglyceride
level is less than 100? (Levels under 150 milligrams per deciliter
are considered normal).
In a randomly...

NOTE: Answers using z-scores rounded to 3 (or more) decimal
places will work for this problem. The population of weights for
men attending a local health club is normally distributed with a
mean of 174-lbs and a standard deviation of 31-lbs. An elevator in
the health club is limited to 34 occupants, but it will be
overloaded if the total weight is in excess of 6460-lbs. Assume
that there are 34 men in the elevator. What is the average weight...
