Conduct a hypothesis test using ! = 0.05 to determine whether the mean time required to accelerate from 0 to 60 mph is the same for compact, mid-size, and luxury cars.
A random sample of 10 compact cars, 10 mid-size cars, and 10 luxury cars were selected. The time (in seconds) each of the randomly selected cars required to accelerate from 0 to 60 mph was looked up on the Autos.com website. The results are presented below.
Car Type Time (in seconds) Required to Accelerate from 0 to 60 mph
Compact 9.3 8.1 10.2 8.8 9.0 9.3 7.7 9.2 9.4 8.6
Mid-Size 6.9 5.7 8.3 7.7 8.6 5.9 6.1 8.8 6.1 7.2
Luxury 5.7 6.3 5.4 4.7 6.2 7.0 5.9 5.3 6.3 5.0
Conduct a hypothesis test using ! = 0.05 to determine whether the
