Problem 1. (5 points). A study of 500 babies looked at the relationship between their weight at birth and the age at which they first slept through the night. The birth weights averaged out to 95 oz with an SD of 15 oz. The ages at which they first slept all night averaged 45 days with an SD of 12 days. The correlation between these two variables was r = : -0.50. Predict the age at which a baby in the 75th percentile of birth weight will first sleep through the night.
