Question

A regression was perforrmed on test data for 37 car models to examine the association between the weight (thousands of pounds) of the car and the fuel efficieicy (rmiles per gallon (MPG)). A partal output from the simple linear regression aralysis is given below. A hypothesis lest is to be perfored to delerrnire if weight of cars is a sigrificant prector of fuel efficiericy of cars. Determiine the vorecl way to get the tesl-slatistic ir this hypothesis lesi. Variable Constant Weight Coefficient 46.08 -4.87 3.412 1.339 Choose the corrert answer helmw 16.08 OB, 3412 1.339 -1.87-16.08 1.339 3.412 48,08 -4.97 1.339 37 O E 487

Explanation / Answer

here as we know that test statistic =coeffiicient of slope /std error of slope = -4.87/1.339

hence option A is correct
