A pediatrician wants to determine the relation that may exist between a child's height and head circumference. She randomly selects 5 children and measures their height and head circumference. The data are summarized below. Complete parts (a) through (f) below. Height (inches), x Head Circumference (inches), y 27.75 17.6 27.5 25.5 17.1 25 260 17.3 17.5 16.9 (a) Treating height as the explanatory variable, x, use technology to determine the estimates of Bo and B1- Bo s bo = 11.2571 (Round to four decimal places as needed.) B1 sb, = 0.2286 (Round to four decimal places as needed.) (b) Use technology to compute the standard error of the estimate, s. Se = 0.0756 (Round to four decimal places as needed.) (c) A normal probability plot suggests that the residuals are normally distributed. Use technology to determine sp. = 0.0310 (Round to four decimal places as needed.)
