Question
Chapter 13, Problem 47E
a)
To determine
To find the factors.
a)
Expert Solution
Answer to Problem 47E
Jumping with or without parachute.
Explanation of Solution
The factor is like variable whose levels can be manipulated by the experiment. Therefore, the factor in this study is Jumping with or without parachute.
b)
To determine
To find the experimental units.
b)
Expert Solution
Answer to Problem 47E
Volunteer skydivers
Explanation of Solution
In this study, the experimental unit is volunteer skydivers.
c)
To determine
To find the placebo.
c)
Expert Solution
Explanation of Solution
In this study, the placebo is parachute that looks real but doesn’t work.
d)
To determine
To find the treatments.
d)
Expert Solution
Answer to Problem 47E
A good-working parachute and a placebo parachute.
Explanation of Solution
In this study, the treatments are good-working parachute and a placebo parachute.
e)
To determine
To find the response variable.
e)
Expert Solution
Answer to Problem 47E
Survival of parachutist or extent of injuries.
Explanation of Solution
In this study, the response variable survival of parachutist or extent of injuries.
f)
To determine
To find the source of variability that would be control.
f)
Expert Solution
Explanation of Solution
In this study, variability would produce by landing surfaces and jump height. Therefore, all jumpers should jump from the same height during the same type of weather conditions on the same type of landing surface. In this way, variability can be control.
g)
To determine
To explain randomization.
g)
Expert Solution
Explanation of Solution
The role of randomization is to assign the people randomly to the parachutes. The random assignment should be done to good working parachutes and placebo parachutes.
h)
To determine
To explain whether the double-blind experiment is possible.
h)
Expert Solution
Explanation of Solution
The volunteer skydivers should not be aware which volunteers get a good-working parachute or a placebo parachute. The people who evaluate the volunteers after the jump should also be unaware which volunteers received which type of parachute. In this way, double blind experiment can be done.
