Chapter 7: Q. 6 (page 462)

You want to take an SRS 50of the 816students who live in a dormitory on a college campus. You label the students 001to 816in alphabetical order. In the table of random digits, you read the entries

95592 94007 69769 33547 72450 16632 81194 14873

The first three students in your sample have labels

(a) 955,929,400

(b) 400,769,769

(c) 559,294,007

(d) 929,400,769

(e) 400,769,335

Short Answer

Expert verified

The first three students in your sample have labels is option (e)400,769,335

Step by step solution

01

Given information

SRS50of816students was labelled as001to816

the table of random digits9559294007697693354772450166328119414873

Find the first three digits in your sample.

02

Explanation

Identify the random digits of yours

The random digits are

9559294007697693354772450166328119414873

Because our largest number is three digits (816), we'll divide the random numbers into three digits apiece. This can be accomplished by omitting the spaces

955929400769769335477245016632811941487....

Identify the labels from 001,002,....816

955and 929are not within 001,002...816400,769are in there,

so those are our first 2769is already included, cannot include a second time.

3rd number is then 335

The three numbers are400,769,335which is option (e).

Most popular questions from this chapter

What does the CLT say? Asked what the central limit theorem says, a student replies, "As you take larger and larger samples from a population, the histogram of the sample values looks mote and more Normal." ls the student right? Explain your answer.

Bad carpet The number of 铿俛ws per square yard is a type of carpet material that varies with mean 1.6铿俛ws per square yard and standard deviation 1.2铿俛ws per square yard. The population distribution cannot be Normal, because a count takes only whole-number values. An inspector studies 200square yards of the material records the number of 铿俛ws found in each square yard, and calculates x, the mean number of 铿俛ws per square yard inspected. Find the probability that the mean number of 铿俛ws exceeds 2 per square yard. Follow the four-step process.

Students on diets A sample survey interviews an SRS of 267college women. Suppose (as is roughly true) that 70% of college women have been on a diet within the past 12 months. What is the probability that 75% or more of the women in the sample have been on a diet? Follow the four-step process.

Scooping beads A statistics teacher fills a large container with 1000white and 3000red beads and then mixes the beads thoroughly. She then has her students take repeated SRSs of 50beads from the container. After many SRSs, the values of the sample proportion p藛 of red beads are approximated well by a Normal distribution with mean of 0.75and standard deviation of 0.06.

(a) What is the population? Describe the population distribution. (b) Describe the sampling distribution of p藛. How is it different from the population distribution?

Bottling cola A hattling compamy uses a fillimg maichine to fill plastic botles with cola. The bottles are supposed to contain 300milliliters (ml) . In fact, the contents vary according to a Normal distribution with mean 渭=298ml and standard deviation 蟽=3ml

(a) What is the probability that in individual bottle contains less than 295ml? Show you work.

(b) What is the probability that the mean contents of six randomly selected bottles is less than 295ml? Show your work.
