Transcribed Image Text: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
OD. Ho: Po=0
Hi Bo=0
27.75
17.6
27 27.5 25.5 26.75
17.5 17.5 17.1 17.3
Determine the P-value for this hypothesis test
P-value = 0.009 (Round to three decimal places as needed.)
What is the conclusion that can be drawn?
A. Reject Ho and conclude that a linear relation exists between a child's height and head circumference at the level of significance α = 0.01.
OB. Do not reject Ho and conclude that a linear relation does not exist between a child's height and head circumference at the level of significance α=0.01.
OC. Do not reject Ho and conclude that a linear relation exists between a child's height and head circumference at the level of significance α=0.01.
D. Reject Ho and conclude that a linear relation does not exist between a child's height and head circumference at the level of significance α = 0.01.
(e) Use technology to construct a 95% confidence interval about the slope of the true least-squares regression line,
