Answer:
0.451751 is the proportion of variability of Gini Coefficient explained by our least squares lines
Step-by-step explanation:
Given
To predict: Gini by year
Required
Interpret the R squared
In statistics, r squared measures the extent to which the variance of one variable explains the variance of the other variable.
In this question, the variable to predict is Gini:
From the list of options, (c) is correct
Answer:
Maya --->
Amy ---->
see the procedure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Let
m ---> the number of minutes
p ---> the number of puzzles
In this problem, the relationship between the variables m and p represent a proportional variation
so
Maya
it takes Maya 30 minutes to solve 5 logic puzzles
we have
m=30, p=5
Determine the value of the constant of proportionality k
substitute the given values
The value of the constant k is the same that the slope or unit rate
The equation is equal to
Amy
it takes Maya 28 minutes to solve 4 logic puzzles
we have
m=28, p=4
Determine the value of the constant of proportionality k
substitute the given values
The value of the constant k is the same that the slope or unit rate
The equation is equal to
