a. interpret the corresponding 95% confidence intervals for both Birth weight and Age. b. What is the predicted average SBP of an infant born with birth weight 8lbs (128oz) measured at 3 days old? c. 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:SHOW ALL WORK. Interpret confidence intervals and explain the conclusions
from hypothesis tests. For all hypothesis tests, clearly state the null and
alternative hypotheses, the significance level, the test statistic, the p-value, and
your conclusion. If you are using a t-statistic, clearly note how many degrees of
freedom you have.
