12. A pediatrician wants to determine the relation that exists between a child's height (x) and head circumference (y). She randomly selects 11 children from her practice, measures their heights and head circumferences and obtains the following data. Height (x) Head Circumfernce ly) 27.5 24.5 17.5 17.1 25.5 26 17.1 17.3 25 16.9 27.75 26.5 17.6 17.3 27 17.5 26.75 26.75 27.5 17.3 17.5 17.5 a) Calculate the least regression line y=bo+bıx b) Calculate a 95% Confidence Interval about the slope of the least regression line. Let x*=35
