A motorcycle service manage has been using a model that can run an average top speed of 45 kph. A new model is being considered to replace all the motorcycle in service. Then, the company manager gained access to data of 16 motorcycles of the new model and computed the following statistics: Mean = %3D 43.5 kph, Standard dev = 3.0 kph. At alpha = 0.05, does %3D sample evidence indicate that the average top speed of the new motorcycle is greater than 45 kph? Note: Explicitly perform all necessary steps in hypothesis testing
