Question below:

3. You can see a scatter-plot for "Armspan" and "RightFoot", the right foot length. The equation of the regression line predicting length RightFoot of "RightFoot" is y = -22.5 + 0.30x, R2 = 0.28 600 500 a) Identify and interpret the slope of the line. b) Identify the y-intercept. Is it meaningful? 400 c) One of the students has armspan of 162 300 C inches and a RightFoot measure of 24 inches. Find the predicted measure of RightFoot for 200 this student. 100-0 O d) What is the residual? ofa e) Give an interpretation of R in context of 200 400 600 800 1000 ArmSpan data. Line Intercept Slope SSE O User 26.8429 526350.588 Regression 22.4886 0.3008 378299.272 f) Using the value of R = 0.28 and the summary statistics, Column n Mean Std. dev. show how the slope and y-intercept are calculated. RightFoot 117126.84286921.210193 ArmSpan 1171 164.0085437.398643
