1. True or False: In cluster sampling, subjects are pulled from the population in groups.

2. True or False: Sampling Error is only considered to be committed or caused by the researcher.

A. Age of your car

B. Color of your hair

C. Name of your pet

D. Length of your commute to campus

E. Height of your car

F. Height of 20 4 year olds

Expert Solution

1. True, beacuse in cluster sampling the cluster of the population is used as the sampling unit rather than individuals. The population is divided into clusters and a cluster is chosen randomly as sample.

2. True, since it is the work of a researcher to draw the samples from the population and it can be reduced by researcher by designing careful sample designs, collect large enough samples adn by having a multiple contacts to assure a representative response.

3. Dependent Variable is defined as the outcome variable as the output of this variable depends on the independent variable or explanatory variables.
y=xb+e; where y is dependent variable and x is independent variable.

4. weight of a package of hamburger meat, the weight of a child, The height of a building are the example of continuous variables as we cannot count it wehereas no. of people and chairs are countable.

5. Age of your car, Length of your commute to campus,Height of your car, Height of 20 4 year olds are the example of quantitative data as it represents the measures of values and can be expressed as numbers, they are numeric variables. They represent quantity whereas name and colour doesn't represent quantity, they represent quality.
Quantitative=Quantity, Qualitative=Quality

1-6:True or False? 1) The sampling distribution of a statistic is the distribution that is formed using the computed statistic from a every possible sample, only of a given size, taken from the population. 2) The mean of the sampling distribution of a sample mean equals the population mean divided by the square root of the sample size. 3) The standard deviation of the sampling distribution of a sample mean equals the population standard deviation divided by the square root...

Select True or False True False 1. Conclusions and estimates about a population based on sample data are not always going to be correct. For this reason measures of reliability, such a significance level and confidence level, should be built into the statistical inference. True False 2. The confidence level is the proportion of times that an estimating procedure will be wrong. True False 3. Statistical inference is the process of making an estimate, prediction, or decision about a population...

1.Choose all that apply(2). For a cluster sample All subjects have an equally likely chance of being selected Clusters are usually determined by convenience All subjects will be measured in a selected cluster Clusters have to be of equal size An equal number of subjects will be measured in every cluster unanswered 2.A sampling bias occurs when The sample is not selected at random Subjects were influenced to respond a certain way Subject did not respond Subjects were given leading...

Auditing True or False: 1. Audit sampling is the performance of a procedure on less than 100% of the items in the population to arrive at a conclusion about the population. 2. Non-statistical sampling should never be used. 3. When using probability-proportional-to-size sampling, each item in the population is given a probability of selection in proportion to its recorded amount. 4. In a computerized environment, there may be less documentation of transactions that have occurred. 5. When utilizing an EDI...

TRUE OR FALSE 1. A t-test is used when the population standard deviation is known. 2. The degrees of freedom in a t-test is one less than the margin of error. 3. A confidence interval can only be found when the standard deviation of the population is known. 4. The margin of error for a t-test is calculated using the sample mean. 5. The null hypothesis is a claim made about the sample. 6. The significance level is denoted by...
