For the problems that require...

For the problems that require a written response, please use proper English and complete sentences. Your definitions and explanations should be explicit and meaningful from a statistical viewpoint. Where appropriate, fill in the space with the required missing term or value. For the computational problems, show all essential work, but please make use of your calculator's statistical keys. There are 21 problems each worth five points. Express your answers, as appropriate, in reduced fractional form or rounded to the nearest hundredth or thousandth or to the nearest tenth of a percent.

1. An experiment consists of matching a type of fertilizer (type X, type Y) with a lighting condition (low, medium, high) and a water classification (soft, hard). How many matches are needed for a complete experiment?

2. A pizzaria has the following toppings available: olives, peppers, sausage, mushrooms, and pineapple. The Tri-Pizza Special is a pizza made with 3 different toppings. How many different pizzas make-up the Tri-Pizza Special?

3. A dodecahedron is a 12-sided die in which each side is a regular pentagon. For a particular game, that die has 1 side that is purple, 2 that are orange, 4 that are yellow, and 5 that are green. Assume that the die must always land with a side up. If the die is tossed twice, what is the probability that both tosses land with the yellow side up?

4. Using the standard normal distribution, find: P(z < 0.08)

5. One-fourth of a certain breed of rabbits are born with long hair. Consider fifteen newly born rabbits of this breed. What is the probability that, of the 15 newly born rabbits, exactly 8 of them are born with long hair?

6. A game at a local carnival consists of rolling a six sided die, where the sides are distinctly numbered 1 to 6 (one number per side of the die), twice. If doubles are rolled, then the player wins $25. If two consecutive numbers are rolled (for example a 2 and then a 3 or a 5 and then a 4) then the player wins $15. Any other roll results do not win anything. It costs $10 to play this game. Either construct a probability distribution for a player’s expected winnings or find a player’s expectation.

7. In a certain metropolitan area, 40% of the adults attend church regularly. If a random sample of 10 adults is selected from this population, what is the probability that seven or more of them attend church regularly?

8. The GPA’s (grade point averages) of students at The University are normally distributed with a mean of 2.5 and a standard deviation of 0.75. The top 3% of the students are to be given special recognition. What (minimum) GPA does a student need in order to qualify?

9. The times students take to complete a MATH 103 final exam are normally distributed with a mean of 110 minutes and a standard deviation of 15 minutes. Find the probability that someone takes between 90 and 110 minutes to complete the final exam.

10. The mean weekly income of a sample of top executives is $1,500. The standard deviation of the sample is $200. Interpret the z-value for an income of $1,100.

11. View Part 11 of your spreadsheet, which contains statistics for your trimmed set of price data. Based upon the sample size of those trimmed prices, would it be reasonable to assume that the distribution of all possible sample means, computed from all possible random samples of the same size as the sample size shown for the trimmed prices, is approximately normally distributed? Yes or no, and why or why not?

12. A survey found that 30% of pet owners had their pets bathed professionally rather than doing it themselves. If 9 pet owners are randomly elected, find the probability that at least one of them has his/her pets bathed professionally.

For Problems 13-15, refer to the information below.

Allergic reactions to poison ivy are caused by plant oils. Below is a table summarizing the results of a research study in which a random sample of 1000 people with known allergies to poison ivy participated.

Time In Which Oil Was Washed Off

Reaction Within 5 min. After 5 min. Totals

None 420 50 470

Mild 60 330 390

Strong 30 110 140

Totals 510 490 1000

If a participant is randomly selected,

13. Find the probability that this person had no reaction given that the oil was washed off within 5 minutes.

14. Find the probability that this person washed off the oil after 5 minutes and had a strong reaction.

15. Find the probability that this person washed off the oil within 5 minutes or had a mild reaction.

For Problems 16 and 17, refer to the information below.

A realtor took a survey of all homes in his/her county to determine the percentages of homes with various numbers of swimming pools and the following distribution
