How do we decide whether to use a z test or a t test when testing a hypothesis about a population mean? THE DISK BRAKE CASE National Motors has equipped the ZX-900 with a new disk brake system. We define the stopping distance for a ZX-900 as the distance (in feet) required to bring the
What assumptions must be met in order to carry out the test about a population mean based on the t distribution? THE DISK BRAKE CASE National Motors has equipped the ZX-900 with a new disk brake system. We define the stopping distance for a ZX-900 as the distance (in feet) required to bring the automobile
