e. What is the predicted average SBP of an infant born with birth weight 8lbs (1280z) measured at 3 days old? f. Calculate the Pearson correlation between Age and Birth weight, and test if this correlation is significant at the 0.05 level. Does this answer surprise you, why or why not?

Question
I only need d,e, and f answered! I just included the rest to give full context.

Transcribed Image Text:e. What is the predicted average SBP of an infant born with birth weight 8lbs
(1280z) measured at 3 days old?
f. Calculate the Pearson correlation between Age and Birth weight, and test
if this correlation is significant at the 0.05 level. Does this answer surprise
you, why or why not?

Transcribed Image Text:1. Consider the following data collected regarding infant blood pressure, age, and
birth weight:

a. Fit a model
to predict SBP from birth weight and Age. Present the
equation of the least-squares regression line.
b. Interpret the beta coefficients for Birth weight and Age.
c. Are Birth weight and/or Age significantly associated with SBP at the alpha
= 0.05 level?
d. Interpret the corresponding 95% confidence intervals for both Birth weight
and Age.
