1.) Below are cellular data speeds from Sprint and Verizon measured at different airports Sprint: 13.0 30.4 15.2 2.4 2.7 2.1 0.8 1.6 5.6 Verizon: 38.5 55.6 22.4 14.1 23.1 24.5 6.5 21.5 25.7 At a= 0.05 a.) Calculate r and determine if there is linear correlation. State the critical value. b.) If there is linear correlation, find the regression line. If not, skip this step. c.) LAX has Sprint speed of 10.2. Predict Verizon’s speed at LAX. 1a.) r= ____________ Linear? ___________ CV: ____________ b.) ____________________ c.) ___________________
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
