# Question #526b2

Dec 16, 2017

-There are more points above the best fit line than below it. Yes (barely) (4 vs. 3)
-The slope of the best fit line is positive. YES (barely) - 0.2554

#### Explanation:

-Data points are more clustered than spread out. NO
-The residual for point (39,940) is 12.75. NO
-The equation for the best fit line is y=−6.083x+930.016. NO

-There are more points above the best fit line than below it. Yes (barely)

-The correlation coefficient is 0.2. NO
-The equation for the best fit line is y=6.083x+930.016. NO

-The slope of the best fit line is positive. YES (barely)

First, construct the linear regression best-fit line. Calculate/record the slope and equation. Observe for distribution. Compute the correlation coefficient R.

${R}^{2} = 0.000027796$, Slope = 0.2554, Intercept = 1129
Line = $N a = 0.2554 \left(F a t\right) + 1129$
