Chapter 5: Q. 27E (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 310(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

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

Hence, the correct option is (c).

Step by step solution

01

Step 1. Given information

3of the 10shots are made.

02

Step 2. Explanation for correct option

Although, it is observed that there are three dots above 3and one dot to the left in the dot plot of the previous exercise and therefore it is likely to get 3or fewer made shots when the shooter has 47%probability of making the shot.

This then implies that it is likely to get the sample results and therefore there is no convincing evidence that researcher is less than a 47%shooter (as it is plausible to make 3or fewer shots by chance alone).

Hence, the correct option is (c).

Which one of the following is true about the events “Owner has a Chevy” and

“Owner’s truck has four-wheel drive”?

a. These two events are mutually exclusive and independent.

b. These two events are mutually exclusive, but not independent.

c. These two events are not mutually exclusive, but they are independent.

d. These two events are neither mutually exclusive nor independent.

e. These two events are mutually exclusive, but we do not have enough information to determine if they are independent.

The security system in a house has two units that set off an alarm when motion is

detected. Neither one is entirely reliable, but one or both always go off when there is

motion anywhere in the house. Suppose that for motion in a certain location, the

probability that detector A goes off and detector B does not go off is 0.25, and the

probability that detector A does not go off is 0.35. What is the probability that detector

B goes off?

a.0.1b.0.35c.0.4d.0.65e.0.75

Checking independence Suppose C and D are two events such that

P(C)=0.6,P(D)=0.45,and P(C∩D)=0.3Are events C and D independent? Justify your answer.

BMI (2.2, 5.2, 5.3) Your body mass index (BMI) is your weight in kilograms divided by

the square of your height in meters. Online BMI calculators allow you to enter weight in

pounds and height in inches. High BMI is a common but controversial indicator of being

overweight or obese. A study by the National Center for Health Statistics found that the

BMI of American young women (ages 20 to 29) is approximately Normally distributed

with mean 26.8 and standard deviation 7.4.

27

a. People with BMI less than 18.5 are often classed as “underweight.” What percent of

young women are underweight by this criterion?

b. Suppose we select two American young women in this age group at random. Find the

probability that at least one of them is classified as underweight.

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.
