Expert Solution & Answer

To determine

Whether the sampling is dependent or independent.

To indicate: Whether the response variable is qualitative or quantitative variable.

Answer to Problem 1RE

The sampling isdependent.

The response variable is quantitative variable.

Explanation of Solution

Given info:

There are 2 groups in which 20 subjects are randomly allocated for group 1 and 20 subjects are randomly allocated for group 1. Also, the subjects are matched by diagnosis.

Justification:

Independent sample:

If the individuals from one sample do not associate with the individuals from other sample, then the two samples are said to be independent samples.

Dependent sample:

If the individuals from one sample is associated with the individuals from other sample, then the two samples are said to be dependent samples.

Here, the subjects are taken from the two groups and the subjects are matched by diagnosis. This indicates that the data are matched according to some inherent relationships. Therefore, the sampling isdependent.

Qualitative Variable:

It is used to classify the individuals on some attribute or characteristic.

Quantitative Variable:

It gives a numerical measurement of the individuals of population. The values of quantitative variables can be added or subtracted to get meaningful result.

Also, the response variable is the length of stay. Hence, the response variable gives a numerical measurement of the individuals of a sample.

Thus, the response variable is quantitative variable.

A well-known company predominantly makes flat pack furniture for students. Variability with the automated machinery means the wood components are cut with a standard deviation in length of 0.45 mm. After they are cut the components are measured. If their length is more than 1.2 mm from the required length, the components are rejected. a) Calculate the percentage of components that get rejected. b) In a manufacturing run of 1000 units, how many are expected to be rejected? c) The company wishes to install more accurate equipment in order to reduce the rejection rate by one-half, using the same ±1.2mm rejection criterion. Calculate the maximum acceptable standard deviation of the new process.
