A simple random sample (SRS) is

(a) any sample selected by using chance.

(b) any sample that gives every individual the same chance to be selected.

(c) a sample that gives every possible sample of the same size the same chance to be selected.

(d) a sample that doesn’t involve strata or clusters.

(e) a sample that is guaranteed to be representative of the population.

Short Answer

Expert verified

The correct option is (c) a sample that gives every possible sample of the same size the same chance to be selected.

Step by step solution

01

Given information

A simple random sample (SRS) is given.

02

Concept

A simple random sample is a type of sample where every sample of the same size has the same chance of selection.

03

Explanation

A simple random sample is one in which all samples of the same size have the same chance of being chosen. The probability of selecting each sample in a basic random sample is the same.

A simple random sample is a portion of the population selected at random from the target population. As a result, the best solution is (c).

Internet telephone calls You can use Voice over Internet Protocol (VoIP) to make long-distance

telephone calls over the Internet. How will the cost affect the use of this service? A university plans an experiment to find out. It will offer the service to all 350 students in one of its dormitories. Some students will pay a low flat rate. Others will pay higher rates at peak periods and very low rates off-peak. The university is interested in the amount and time of use and inthe effect on the congestion of the network.

When we take a census, we attempt to collect data from

(a) a stratified random sample.

(b) every individual selected in an SRS.

(c) every individual in the population.

(d) a voluntary response sample.

(e) a convenience sample.

Sampling frame Ideally, the sampling frame in a sample survey should list every individual in the population, but in practice, this is often difficult.

Suppose that a sample of households in a community is selected at random from the telephone directory. Explain how this sampling method results in under coverage that could lead to bias.

Reducing unemployment Will cash bonuses speed the return to work of unemployed people? A state department of labor notes that last year 68%of people who filed claims for unemployment insurance found a new job within 15weeks. As an experiment, this year the state offers $500to people filing unemployment claims if they find a job within 15weeks. The percent who do so increases to 77%. What flaw in the design of this experiment makes it impossible to say whether the bonus really caused the increase? Explain.

Do you trust the Internet? You want to ask a sample of high school students the question “How much do you trust information about health that you find on the Internet—a great deal, somewhat, not much, or not at all?” You try out this and other questions on a pilot group of 5 students chosen from your class. The class members are listed at the top right.

(a) Explain how you would use a line of Table D to choose an SRS of 5 students from the following list. Explain your method clearly enough for a classmate to obtain your results.

(b) Use line 107 to select the sample. Show how you use each of the digits.
