<h2>Option D: a call to a private method of the superclass</h2>
Explanation:
Option a: a method with the "same signature" is allowed in the subclass. There will not be any confusion because the object which is trying to call the method will decide whether to call the sub class or super class.
Option b: a call to a super class constructor is possible because, when you create an object of sub class automatically the super class constructor will be called. Even the sub class constructor can call the super class constructor explicitly.
Option c: A subclass can create method that's not defined by the super class
Option D: a private method is private inside the class and hence even the object of that class cannot access.
Answer:
(a)
(b)
(c) Smoking increases the time to fall asleep
Explanation:
Solving (a): The sample mean of each group
Mean is calculated as:
So, we have:
<u>Smokers</u>
and
Non Smokers
and
Solving (b): The standard deviation of each group
This is calculated as:
For smokers
So:
For non-smokers
So:
Solving (c): Impact of smoking on time to sleep
In (b), we have:
--- smokers
--- non-smokers
<em>Smokers have larger standard deviation (i.e. large variability) than non-smokers. This means that smokers require more time to fall asleep.</em>
