Question
Chapter 13, Problem 16E
a)
To determine
To find the type of the study.
a)
Expert Solution
Answer to Problem 16E
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 16E
The 5 racing grey hounds.
Explanation of Solution
The subjects studied were racing greyhounds.
c)
To determine
To find the factors and number of levels.
c)
Expert Solution
Answer to Problem 16E
Diet with varying amounts of vitamin C with 3 levels.
Explanation of Solution
In this study, the factor is Diet with varying amount of vitamin C. Therefore, there are 3 levels which might be specified values of the factor.
d)
To determine
To find the number of treatments.
d)
Expert Solution
Answer to Problem 16E
3
Explanation of Solution
In this study, there are 3 treatments.
e)
To determine
To find the response variable.
e)
Expert Solution
Answer to Problem 16E
The response variable is speed of the greyhounds.
Explanation of Solution
In this study, the response variable is running speed of the greyhounds.
f)
To determine
To identify the type experiment.
f)
Expert Solution
Answer to Problem 16E
Matched design
Explanation of Solution
The experiment used a matched design. That is, each of the greyhounds was given each of the 3 of diet in random order.
g)
To determine
To identify whether the study is blinded or double blinded.
g)
Expert Solution
Answer to Problem 16E
The experiment is not determined as blinded.
Explanation of Solution
The experiment is cannot determine because it does not have any indication about blind.
h)
To determine
To explain the scope and conclusions.
h)
Expert Solution
Explanation of Solution

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.
