We have to find the graph of the hyperbola whose equation is given as:.We know that the general equation of the hyperbola is given by:where the focus of the hyperbola are at the points:(a,0) and (-a,0).Hence, the focus of the given hyperbola are the points:(3,0) and (-3,0).The figure of the hyperbola is attached to the figure.
Answer:
Correlation will not change.
Correlation coefficient = -0.72
Step-by-step explanation:
We are given the following in the question:
Correlation coefficient between hours spent studying and hours spent on the Internet = -0.72
Properties of correlation coefficient:
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- It is not affected by the units of the variable or change in units of the variable.
Thus, if the units of each variable is changed from hours to minutes, the correlation coefficient remains the same between minutes studying and minutes spent on the Internet.
