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).

For Exercises 1 to 4, identify the population, the parameter, the sample, and the statistic in each setting

Hot turkey Tom is cooking a large turkey breast for a holiday meal. He wants to be sure that the turkey is safe to eat, which requires a minimum internal temperature of 165°F. Tom uses a thermometer to measure the temperature of the turkey meat at four randomly chosen points. The minimum reading in the sample is 170°F

Larger sample Suppose that the blood cholesterol level of all men aged 20-34follows the Normal distribution with mean μ=188milligrams per deciliter (mg/dl) and standard deviation σ=41mg/dl

(a) Choose an SRS of 100men from this population What is the sampling distribution of x?

(b) Find the probability that xestimates μwithin ±3mg/dl. (This is the probability thatx¯takes a value between 185and191mg/dl.) Show your work.

(c) Choose an SRS of 1000men from this population. Now what is the probability that xfalls within±3mg/dlofμ? show your wrok.in what sense is the large sample "better".

The candy machine Suppose a large candy machine has 15%orange candies. Use Figure 7.13 (page 435) to help answer the following questions.

(a) Would you be surprised if a sample of 25 candies from the machine contained 8 orange candies (that's 32%orange)? How about 5 orange candies ( 20%orange)? Explain.

(b) Which is more surprising: getting a sample of 25 candies in which 32%are orange or getting a sample of 50 candies in which 32% are orange? Explain.
