MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Leonardo da Vinci (1452-1519) drew a sketch of a man, indicating that a person's armspan (measuring across the back with arms outstretches he person's height. To test this claim, we measured eight people with the following results Person 2 Armspan (ir leight (inches) 69 62 65 67 67 63 LA USE SALT (a) Draw a scatterplot for armspan and height. Use the same scale on both the horizontal and vertical axes. O Height Height Height (in) (in) (in) 75 75 75 70 70 . . . 65 65 65 Armspan Armspan Armspan 65 70 75 (in) 60 65 70 75 (in) 65 70 75 (in) Height (in) 75 Armspan 65 70 75 (in) Describe the relationship between the two variables. O There is a negative linear relationship between armspan and height. O There is no relationship between armspan and height. There is a positive linear relationship between armspan and height. (b) Calculate the correlation coefficient r relating arms in and height. (Round your answer to four decimal places.) (c) If you were to calculate the regression line for predicting height based on a person's armspan, how would you estimate the slope of this line? Since DaVinci suggested that a lope of the line should be approximately equal to 1. O Since DaVinci suggested that a person's armspan is roughly equ eight, the slope of the line should be negative. Since DaVinci suggested that a person's armspan is the slope of the line should be greater than 1. Since DaVinci suggested that a person's armspan is roughly equal to his height, the slope of the line should be approximately equal to o. (d) Find the regression line relating armspan x to a person's height y. (Round your numeric values to three decimal places.) e) If a person has an armspan of 63 inches, ght (in inches) to be? (Round your answer to two decimal places.) in
