| In recent years, a growing array of entertainment options competes for consumer time. By 2004, cable television and radio surpassed broadcast television, recorded music, and the daily newspaper to become the two entertainment media with the greatest usage (The Wall Street Journal, January 26, 2004). Researchers used a sample of 15 individuals and collected data on the hours per week spent watching cable television and hours per week spent listening to the radio. |
| a. Use a .05 level of significance and test for a difference between the population mean usage for cable television and radio. What is the p-value? |
| b. What is the sample mean number of hours per week spent watching cable television? What is the sample mean number of hours per week spent listening to radio? Which medium has the greater usage? |

1.13. Problem. (Section 3.4) Three black boxes are labeled with Roman numerals I, II and III. • Box I contains four red chips and three blue chips. • Box II contains two red chips and five blue chips. • Box III contains seven red chips and no blue chips. Solve each of the following problems.
(a) Suppose a box is selected at random and three chips are drawn at random from the box. If all three chips are red, what is the probability they were drawn from Box I?
(b) Suppose one chip is selected at random from each box. If two of the three chips drawn are red chips, what is the probability that the chip drawn from Box II was red?
(c) Suppose three chips are randomly selected from Box I and placed in Box III. If a chip subsequently drawn randomly from Box III is blue, what is the probability that all three chips moved from Box I to Box III were blue.

ou have just begun work at XYZ Manufacturing Company. Among its benefits offerings is a generous qualified 401(k) plan with an employer match. In 2015, your annual salary is $45,000 and you are age 55. You’ve decided to contribute 10 percent of your annual salary to your 401(k) plan even though the Internal Revenue Service allows you to contribute up to $24,000 in 2015 ($18,000 plus a $6,000 catch up contribution for employees age 50 or more). The annual addition is $53,000.
1 How much more money would you need to contribute to meet the allowable maximum contribution?
2 In 2015, the company offers a $0.75 match for each dollar that you contribute between 3 percent and 6 percent of your annual salary. How much is the company match based on your 10 percent contribution?
3 Based on the sum of your answers to questions 9-9 and 9-10, what is the difference between the IRS maximum annual addition for 2015 and the total contribution to your 401(k) plan?

Goodyear Commercial Retread facility recycles worn or damaged tires to retread two sizes of tires, medium and large, for tractor trailers. To fill one client’s order, they will use a combination of three machines to manufacture the retreads and will need to produce at least 54 medium tires and 59 large tires. In one hour, Machine I can produce 2.5 medium tires and 5 large tires, Machine II can produce 4.5 medium tires and 3 large tires, and Machine III can produce 5 medium tires and 10 large tires. The cost per hour to operate Machine I, II, and III are $8, $9, and $10, respectively. There are two combinations of using the three machines that produce the same minimum cost. What are those two combinations and what is the minimum cost?

A)In a certain state's lottery, 40 balls numbered 1 through 40
are placed in a machine and eight of them are drawn at random. If
the eight numbers drawn match the numbers that a player had chosen,
the player wins $1,000,000. In this lottery, the order in which the
numbers are drawn does not matter.
Compute the probability that you win the million-dollar prize if
you purchase a single lottery ticket. Write your answer as a
reduced fraction.
A single lottery ticket costs $2. Compute the Expected Value, to the state, if 10,000 lottery tickets are sold. Round your answer to the nearest dollar.

6.Geometry John is playing around with probabilities and thinking about rolling a die until he gets a 6. He computes that (5/6)4 is equal to 0.4823, and concludes, “Cool, I’ve got a better than 50% chance of seeing my first six by my fourth roll.” Then Geometry John wonders, “if I roll a die until I roll two sixes, do I have a better than 50% chance of seeing my second six by my eighth roll?” What is the answer to Geometry John’s question? Compute the probability.
7. Suppose you have a shipment of 100 drills, and four of them are defective. If you randomly select ten of the 100 drills and inspect them closely, what is the probability that you will find (at least) one of the defective ones in your sample of ten?
9. If you call a randomly selected person, there is a 1/10 chance that they are left-handed. If you sequentially call randomly selected people until you speak to your third left-handed person, what is the probability that it this takes exactly 10 calls?

|---|---|---|
| Almost no chance | 101 | 113 |
| Some chance but probably not | 142 | 169 |
| A 50-50 chance | 454 | 521 |
| A good chance | 738 | 722 |
| Almost certain | 1163 | 744 |
