Chapter 1: Q6E (page 12)

The California State University (CSU) system consists of 23 campuses, from San Diego State in the south to Humboldt State near the Oregon border. A CSU administrator wishes to make an inference about the average distance between the hometowns of students and their campuses. Describe and discuss several different sampling methods that might be employed. Would this be an enumerative or an analytic study? Explain yourreasoning.

Short Answer

Expert verified

Simple Random sampling and stratified sampling techniques can be used.

This is an enumerative study since the data may be used to create an actionable item by the CSU administrator.

Step by step solution

01

Given information

The number of campuses that the California State University system consists of is 23.

A CSU administrator wishes to make an inference about the average distance between the hometowns of students and their campuses.

02

State the sampling methods that can be employed.

The sampling methods that can be used in the provided scenario are,

Simple Random sampling: Randomly selecting the distance between the hometowns of students and their campuses will eliminate the biases.

Stratified random sampling: This method can be used treating 23 campuses as subgroups and then taking samples from them.

03

Identify the study

In enumerative study, the population under study is finite and seek to provide numerical summaries, conduct tests to give inference about the proposed claim.

Here, A CSU administrator is interested to study the average distance from hometown to campus.

Using these results, he will take the required steps to minimize the distance by changing students from one to other. The action taken by him using the obtained results comes under enumerative study.

How does the speed of a runner vary over the course of a marathon (a distance of 42.195 km)? Consider determining both the time to run the first 5 km and the time to run between the 35-km and 40-km points, and then subtracting the former time from the latter time. A positive value of this difference corresponds to a runner slowing down toward the end of the race. The accompanying histogram is based on times of runners who participated in several different Japanese marathons (鈥淔actors Affecting Runners鈥� Marathon Performance,鈥� Chance, Fall, 1993: 24鈥�30).What are some interesting features of this histogram? What is a typical difference value? Roughly what proportion of the runners ran the late distance more quickly than the early distance?

The cumulative frequency and cumulative relativefrequency for a particular class interval are the sum offrequencies and relativefrequencies, respectively, forthat interval and all intervals lying below it. If, forexample, there are four intervals with frequencies 9,16, 13, and 12, then the cumulative frequencies are 9,25, 38, and 50, and the cumulative relative frequenciesare .18, .50, .76, and 1.00. Compute the cumulativefrequencies and cumulative relative frequencies for thedata of Exercise 24.

The May 1, 2009, issue of the Mont clarian reported the following home sale amounts for a sample of homes in Alameda, CA that were sold the previous month (1000s of $):

590 815 575 608 350 1285 408 540 555 679

  1. Calculate and interpret the sample mean and median.
  2. Suppose the 6th observation had been 985 rather than 1285. How would the mean and median change?
  3. Calculate a 20% trimmed mean by first trimming the two smallest and two largest observations.
  4. Calculate a 15% trimmed mean.

a. What proportion of the contracts involved at mostfive bidders? At least five bidders?

b. What proportion of the contracts involved betweenfive and 10 bidders, inclusive? Strictly between fiveand 10 bidders?

c. Construct a histogram and comment on interestingfeatures.

An experiment to study the lifetime (in hours) for acertain type of component involved putting ten components into operation and observing them for 100hours. Eight of the components failed during that

period, and those lifetimes were recorded. Denote the lifetimes of the two components still functioning after100 hours by 100+. The resulting sample observations were

48 79 100+ 35 92 86 57 100+ 17 29

Which of the measures of center discussed in this section can be calculated, and what are the values of those measures? (Note:The data from this experiment is said to be 鈥渃ensored on the right.鈥�)
