Hypothesis Testing Example 7: Steps in Hypothesis Testing: A manufacturer claims that the thickness of the spearmint gum it produces is 7.5 one- hundredths of an inch. A quality control specialist regularly checks this claim. On one production run, he took a random sample of n= 10 pieces of gum and measured their thickness. The quality control specialist's hypotheses are: HO: 1. Step 1: State Hypotheses 2. Step 2: Select alpha, Draw Picture, Label Critical Values and Rejection Region(s) 3....
