0 will the error in prediction be when the absolute value of the correlation coefficient is 1.
The precise metric used in a correlation analysis to quantify the strength of the linear relationship between two variables is the correlation coefficient. In a correlation report, r stands for the coefficient.
In statistics, correlation coefficients are frequently utilized in the field of investing. They are crucial in fields including performance assessment, quantitative trading, and portfolio composition. The correlation coefficient's numerical component expresses how strong the link is. The variables are more firmly associated and the more predictable changes in one variable will be as the other variable changes the closer the number is to one, whether it is negative or positive.

Answer:
It is reasonable to argue that the <em>invention of the internet</em> had the most influence on expanding American economy.
Explanation:
<u>The internet </u>had a <u>significant effect on cost savings in many sectors of economy, that lowered the prices of products and services</u> and thus increasing living standards and economic growth. It also<u> increased management efficiency to manage companies supply chains more effectively, making transactions cheaper and quicker.</u>
For example, online retail had a revolutionary impact on American economy. Thanks to online retail companies, such as Amazon, shopping has become much faster and easier on the customers side. Customers no longer have to spend time going to the shop, they can make quick purchases online and get their order delivered to the doorstep. On the other hand, online retail companies do not need to rent shopping spaces anymore, they rather need to build super efficient fulfillment centers.

I believe the answer is: learning theory
Learning theories refers to the framework that explain how people obtained data/information, process it as a part of learning, and transform it into knowledge. In social settings, things such as emotion, congitive abiltiy, observation of other behaviours, and the influence of other peiople would be seen as crucial factors that affect people's learning rate.
Answer:
b. Contemplation
Explanation:
The Stages of Change Model focuses on the decision-making of a person and is a model of intentional change. In other words, it is used when the person actively makes the decision of making a change.
The stages of this model are:
- Precontemplation: People do not intend to take action in the foreseeable future (within the next 6 months). They don't even realize that their behavior is problematic.
- Contemplation: People are <u>intending to start the healthy behavior in the foreseeable future (within the next 6 months).</u> They start to recognize that their behavior is problematic but still feel ambivalent towards changing it.
- Preparation: People are ready to take action within the next 30 days. They start taking small steps toward the change and think this can lead to a healthier life.
- Action: People have recently changed their behavior (within the last 6 months) and intend to keep moving forward with it. They now have healthier habits.
- Maintenance: People have sustained their behavior change for over 6 months and they are working to prevent relapses.
- Termination: People have no desire to return to their unhealthy behaviors and they know they won't relapse.
We can see that in the contemplation stage, people still feel ambivalent towards the idea of changing their behavior (and therefore there's no action yet) but they intend to change this behavior within the next 6 months.
Thus, we can say that if a person doesn't exercise (and therefore there's no action) but are thinking of becoming more active in the next six months (intend to change their behavior), this person would be in the stage of contemplation.
