Question

1. What is the equation of the least squares regression line for predicting their weights from their heights? 

2. I'm 35 inches tall. Predict my weight. 

3. What percent of all preschoolers are shorter than me?

4. What percent of all preschoolers are lighter than the weight you predicted for me? 

5. How come you goy such different percentiles in the last two questions? 

The heights and weights of 500 preschoolers have correlation r 0.52.
The average height is 30 inches, the average weight is 40 pounds, the
standard deviation of their heights is 4.6 inches, and the standard
deviation of their weights is 6.2 pounds. Heights and weights are
approximately normally distributed in this particular population.
