The correlation between tree diameter and volume in a data set is 0.9671. How much of the variability of volume is explained by diameter?
A. we need to know the equation of regression.
B. 98.34%
C. 96.71%
D. 93.52%
the variability of volume is explained by diameter be = 93.52 % [ D ]
[ EXPLANATION:-
The correlation (r) between tree diameter and volume in a data set is 0.9671
%
so, we can say that 93.52% of variation in the volume is explained by the independent variable (here, diameter ]

For a certain data set the regression equation is y = 37 + 13x. The correlation coefficient between y and x in this data set _______. must be 0 is negative must be 1 is positive must be 3
Suppose that you are given the following results. Find the correlation coefficient of the data. sx = 2.391, sy = 13.200, b = -4.780 a) 0.155 b) -0.866 c) -0.433 d) -0.155 e) 0.866 f) None of the above Suppose you find that the correlation coefficient for a set of data is 0.841. What is the coefficient of determination and what does it mean? a) 0.841; This means that 84.1% of the variation of y is explained by the LSRL...
Imagine that the linear correlation between variables X and Y is r = 0.35. Further imagine that the mean of variable X is 4 and that the mean of variable Y is 6. If we correctly calculated a simple linear regression equation to predict values of Y (based on the corresponding value of X), how much error could we remove from our predictions, relative to just guessing the mean of Y = 6 for everyone in the data set?
I am trying to compare the variability in the filament diameter
for this data set. I know I need to use an
F-test.
the degrees of freedom is: 168
Can someone help me with this and explain the
interpertation ?

The annual salary and the number of years of teaching experience were recorded for 100 high school teachers in northern Ohio. When the data points were plotted using a scatterplot, the relationship was shown to be linear and positive, with a correlation of r = 0.75 between salary and number of years of teaching experience. If we construct a regression equation to predict salary based on years of teaching experience, approximately what percentage of the variability in salary would be...
