Concept explainers

Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…
Question

I have submitted this question twice, and still am not getting the right answer, please help. 

Complete the table by computing the absolute and relative change.

 

  Time    Value    Absolute Change    Relative Change 
0 26.32 XXXXX XXXXX
1 29.78    
2 33.24    
3 36.7    
4 40.16    
5 43.62    

(i) Which of the following statements are true? Select all that apply.
A. No model can be inferred from the data provided.
B. The data suggest that a linear model would be appropriate.
C. The data suggest that an exponential model would be appropriate.
D. The data show a constant growth rate.
E. The data increase by a fixed amount each year.

(ii) Use the data from the table to construct the appropriate model to predict the value at future times.
What value does your model predict when the time is 9.25?
(Express your answer rounded correctly to the nearest hundredth.)
