Chapter 4 Homework-Katrina Perkins were made for a sample of adult men. A regression line was fit to predict the men's armspan from their The output from several statistical technologies is provided in the accompanying charts. The scatterplot confirms height that the association Click the icon to see the scaterplot and the output from several statistical technologies. between armspan and height is linear.Complete parts a and b. a. Report the equation for predicing armspan from height Use words such as armspan not just x and y Predicted Round to three decimal places as needed.) b. Explain how to find the slope and intercept for each of the provided outputs Explain how to find the slope and intercept for the displayed output. Choose the correct answer below The regression equation is Amspan = 31.1 + 2.14 Height A. The slope is the constant, and the intercept is the number being multiplied by Height O B. The slope is the number being multsiplied by Height, and the intercept is the constant divided by the sample size. O C. The slope is the number being multiplied by Height, and the intercept is the constant. O D. The slope is the constant, and the intercept is the number being mutiplied by Height divided by the sample size.
