Question
Chapter 13, Problem 19E
a)
To determine
To find the type of the study.
a)
Expert Solution
Answer to Problem 19E
This is an experimental study.
Explanation of Solution
First need to understand about the experimental study and observational study:
Experimental study: Assigning people or things to groups and applying some treatment to one group, while the other group does not receive the treatment.
Observation study: In an observational study, measure or survey members of a sample without trying to affect them.
This is an experimental study because the treatment is imposed on the subjects.
b)
To determine
To find the subjects.
b)
Expert Solution
Answer to Problem 19E
Athletes suffering from hamstring injuries.
Explanation of Solution
The subjects studied were athletes suffering from hamstring injuries.
c)
To determine
To find the factors and number of levels.
c)
Expert Solution
Answer to Problem 19E
Type of exercise with 2 levels.
Explanation of Solution
In this study, the factor is type of exercise. There are 2 levels. The static stretching and trunk stabilization.
d)
To determine
To find the number of treatments.
d)
Expert Solution
Answer to Problem 19E
2
Explanation of Solution
In this study, there are 2 treatments.
e)
To determine
To find the response variable.
e)
Expert Solution
Answer to Problem 19E
The response variable is time.
Explanation of Solution
In this study, the response variable is time before the athletes were able to return to sports.
f)
To determine
To identify the type of design.
f)
Expert Solution
Answer to Problem 19E
Completely randomized design.
Explanation of Solution
The experiment used a Completely randomized design.
g)
To determine
To identify whether the study is blinded or double blinded.
g)
Expert Solution
Answer to Problem 19E
The experiment does not used blinded design.
Explanation of Solution
As per overall study, there is no way to identify a blinded design.
h)
To determine
To explain the scope and conclusions.
h)
Expert Solution
Explanation of Solution
There should be any specific exercise program so that athletes can help to determine which exercise program is more effective.

- 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.arrow_forward5. Let X and Y be independent random variables and let the superscripts denote symmetrization (recall Sect. 3.6).
