Chapter 5: Q. 26E (page 312)

A total of 25repetitions of the simulation were performed. The number of makes in each set of 10simulated shots was recorded on the dotplot. What is the approximate probability that a 47%shooter makes 5or more shots in 10attempts?

(a) 510

(b) 310

(c) 1225

(d) 325

(e)47100

Short Answer

Expert verified

The correct option is (c)1225.

Step by step solution

01

Step 1. Given information

The approximate probability that a 47%shooter makes 5or more shots in 10attempts.

02

Step 2. Explanation

There is ‘5’ number is having the highest number of counts which is 9and at number ‘6’ and ‘7’ there are 2and 1dots respectively. So there total numbers of dots are 12out of 25.

Hence, the correct option is (c)

A basketball player claims to make 47%of her shots from the field. We want to simulate the player taking sets of 10shots, assuming that her claim is true.

To simulate the number of makes in 10shot attempts, you would perform the simulation as follows:

a. Use 10 random one-digit numbers, where 0-4are a make and 5-9are a miss.

b. Use 10random two-digit numbers, where 00-46are a make and 47-99are a miss.

c. Use 10random two-digit numbers, where 00-47are a make and 48-99are a miss.

d. Use 47random one-digit numbers, where 0is a make and 1-9are a miss.

e. Use 47random two-digit numbers, where 00-46are a make and 47-99are a miss.

Crawl before you walk (At what age do babies learn to crawl? Does it take

longer to learn in the winter, when babies are often bundled in clothes that restrict their

movement? Perhaps there might even be an association between babies’ crawling age and

the average temperature during the month they first try to crawl (around 6months after

birth). Data were collected from parents who brought their babies to the University of

Denver Infant Study Center to participate in one of a number of studies. Parents reported

the birth month and the age at which their child was first able to creep or crawl a distance

of 4feet within one minute. Information was obtained on 414infants208boysand206girls. Crawling age is given in weeks, and average temperature (in degrees Fahrenheit) is

given for the month that is 6months after the birth month.

a. Make an appropriate graph to display the relationship between average temperature and

average crawling age. Describe what you see.

Some computer output from a least-squares regression analysis of the data is shown.

b. What is the equation of the least-squares regression line that describes the relationship

between average temperature and average crawling age? Define any variables that you

use.

c. Interpret the slope of the regression line.

d. Can we conclude that warmer temperatures 6months after babies are born causes them

to crawl sooner? Justify your answer.

Four-sided dice A four-sided die is a pyramid whose four faces are labeled

with the numbers 1,2,3and4(see image). Imagine rolling two fair, four-sided dice and

recording the number that is showing at the base of each pyramid. For instance, you would

record a 4if the die landed as shown in the figure.

a. Give a probability model for this chance process.

b. Define event A as getting a sum of 5. Find P(A).
