Chapter 5: Q. 27 (page 313)

Suppose this player attempts 10shots in a game and makes only 3of them. Does this provide convincing evidence that she is less than a 47%shooter?

a. Yes, because 3/10(30%) is less than 47%

b. Yes, because she never made 47%of her shots in the simulation.

c. No, because it is plausible (believable) that she would make 3or fewer shots by chance alone.

d. No, because the simulation was only repeated 25times.

e. No, because more than half of the simulated results were less than47%

Short Answer

Expert verified

The correct answer is option (c) No, because it is plausible (believable) that she would make 3or fewer shots by chance alone.

Most popular questions from this chapter

Will Luke pass the quiz ? Luke’s teacher has assigned each student in his class an online quiz, which is made up of 10multiple-choice questions with 4options each. Luke hasn’t been paying attention in class and has to guess on each question. However, his teacher allows each student to take the quiz three times and will record the highest of the three scores. A passing score is 6or more correct out of 10. We want to perform a simulation to estimate the score that Luke will earn on the quiz if he guesses at random on all the questions.

a. Describe how to use a random number generator to perform one trial of the simulation. The dotplot shows Luke’s simulated quiz score in 50trials of the simulation.

b. Explain what the dot at 1represents.

c. Use the results of the simulation to estimate the probability that Luke passes the quiz.

d. Doug is in the same class and claims to understand some of the material. If he scored 8points on the quiz, is there convincing evidence that he understands some of the material? Explain your answer.

Income tax returns Here is the distribution of the adjusted gross income (in thousands of dollars) reported on individual federal income tax returns in a recent year:

a. What is the probability that a randomly chosen return shows an adjusted gross income of \(50,000 or more?

b. Given that a return shows an income of at least \)50,000, what is the conditional

probability that the income is at least $100,000?

Union and intersection Suppose A and B are two events such that P (A)=0.3, P (B)=0.4, and

P (A∪B)=0.58. Find P (A∩B).

Which of the following is a correct way to perform the simulation?

a. Let integers from 1to34represent making a free throw and 35to50represent missing a free throw. Generate 50random integers from1to50. Count the number

of made free throws. Repeat this process many times.

b. Let integers from 1to34represent making a free throw and 35to50represent missing a free throw. Generate 50 random integers from 1 to 50 with no repeats

allowed. Count the number of made free throws. Repeat this process many times.

c. Let integers from1to56represent making a free throw and 57to100represent missing a free throw. Generate 50 random integers from1to100.Count the number of made free throws. Repeat this process many times.

d. Let integers from localid="1653986588937" 1to56represent making a free throw and localid="1653986593808" 57to100represent missing a free throw. Generate 50 random integers from localid="1653986598680" 1to100with no repeats allowed. Count the number of made free throws. Repeat this process many times.

e. None of the above is correct.

Colorful disksA jar contains 36disks: 9each of four colors—red, green, blue, and Page Number: 328yellow. Each set of disks of the same color is numbered from 1to 9. Suppose you draw one disk at random from the jar. Define events R: get a red disk, and N: get a disk with the number 9.

a. Make a two-way table that describes the sample space in terms of events Rand N.

b. Find P(R)and P(N).

c. Describe the event “Rand N” in words. Then find the probability of this event.

d. Explain why P(RorN)≠P(R)+P(N) Then use the general addition rule to computeP(RorN).
