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 26 25 27.75 27.5 26.75 Head Circumference (inches), y 17.3 16.9 17.6 17.5 17.3 (a) Treating height as the explanatory variable, x, use technology to determine the estimates of beta 0 and beta 1. beta 0almost equalsb 0equals nothing (Round to four decimal places as needed.) beta 1almost equalsb 1equals nothing (Round to four decimal places as needed.) (b) Use technology to compute the standard error of the estimate, s Subscript e. s Subscript eequals nothing (Round to four decimal places as needed.) (c) A normal probability plot suggests that the residuals are normally distributed. Use technology to determine s Subscript b 1. s Subscript b 1equals nothing (Round to four decimal places as needed.) (d) A normal probability plot suggests that the residuals are normally distributed. Test whether a linear relation exists between height and head circumference at the alphaequals0.01 level of significance. State the null and alternative hypotheses for this test. Choose the correct answer below. A. Upper H 0: beta 0equals0
