question 44

Multiple Choice

A weight loss centre provided a loss for 72% of its participants.The centre's leader decides to test a new weight loss strategy to see if it's better and receives a P-value of 0.23.What is reasonable to conclude about the new strategy using α = 0.10?

• A)There is a 77% chance of the strategies being equally effective.
• B)There is a 23% chance of the strategies being equally effective.
• C)If the percentage of participants who lose weight has not changed (not increased),then there is a 23% chance of seeing the increase in the percentage of participants who lose weight that we observed (or higher)from natural sampling variation.At α = 0.10,we reject the null hypothesis and conclude that the new strategy is effective.
• D)We can say there is a 23% chance of not seeing the strategies being equally effective in the results we observed from natural sampling variation.We conclude the new strategy is more effective.
• E)If the percentage of participants who lose weight has not changed,then there is a 23% chance of seeing the increase in the percentage of participants who lose weight that we observed (or higher)from natural sampling variation.At α = 0.10,we fail to reject the null hypothesis that the percentage has not changed from 72%.There is insufficient evidence to conclude that the new strategy is effective.

Definitions:

Object Oriented Programming

A programming paradigm based on the concept of "objects", which can contain data, in the form of fields, and code, in the form of procedures.

Encapsulation

A fundamental principle of object-oriented programming that restricts direct access to an object's components and can prevent the accidental modification of data.

Inheritance

A mechanism in object-oriented programming where a new class is derived from an existing class, inheriting its attributes and behaviors.

Polymorphism

Polymorphism is a concept in object-oriented programming that allows objects of different classes to be treated as objects of a common superclass, enabling a single interface to control the access to the specific method implementations.
