Normal and special cause variation are managed very differently. How would you know which type you are responding to without the process limits?
The F test describes the ratio of two sources of variability: that for subjects treated differently and that for subjects treated similarly. Describe is there any sense in which the t test for two independent groups can be viewed likewise?
Miss America winners from the 1920's and 1930's had a average BMI of 19.4. A sample of recent winners had reported BMIs of 18.7, 18.7, 18.5, 19.2, 19.3, 18.7, 18.6, 19.8, 19, 19.6, and 19 . Do recent winners appear to be significantly different from those in the 1920s and 1930s? (assume normality). Show all the steps of a hypothesis.
