Use the value of the linear correlation coefficient r to find the percentage of the total variation that can be explained by the

Pie

Answer:

5.47% of the total variation between the two variables can be explained by the regression line.

Step-by-step explanation:

Given :

R value = 0.234

The R value is the correlation Coefficient ; which gives the type and level of correlation between two variables.

However, to Obtian the percentage variation which can be explained by by the regression line, we have to obtain the Coefficient of determination, R².

R² value is Obtained by taking the squared of the correlation Coefficient

Hence,

R² = 0.234² = 0.054756

R² = 0.05476 * 100% = 5.4756%

Hence, R² = 5.48%

This is interpreted as ; 5.47% of the total variation between the two variables can be explained by the regression line.

Put these in point slope form !!

quester [9]

point slope form formula { (y-y1) = m (x-x1) }

so 1. (y-3) = 1/8 (x-3)

2. ( y- 30 ) = -4 (x-6)

3. ( y -7) = 0.25 (x +8)

4 . ( y -2 ) = 1 ( x-0)

Slope of equation :- The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.
