the population distribution of sweetness losses will be close to Normal. Here are the sweetness losses (sweetness before storage minus sweetness after storage) found by tasters from a random sample of 10 batches of a new cola recipe: Are these data good evidence that the cola lost sweetness? Carry out a test to help you answer this question. State: = 0 versus > 0, where is the actual mean amount of sweetness loss. Plan: One-sample test for H0: Ha: t μ μ μ μ. The sample was randomly selected. Previous experience tells us that sweetness losses will be close Random: Normal: to Normal.
