In experiment to study the relation between the time waiting in line, y (minutes), to get to the head of the checkout line at her favorite grocery store and the number of persons ahead in line, x, a student collected the following statistics:
n = 9 , , Sxx = 9.4 , Syy = 17.8 , Sxy = 12.2
Find the equation of the least squares fitted line.
Round your answers to two decimal places.
Depict your answer in the form:
y = 1.60+1.30*x
y = 1.84+1.30*x
y = -1.60+1.30*x
y = 1.84-1.30*x
