a$.$ A sample of $50$ data points can be considered statistically significant: Yes $\_\_\_\_$; No$\_\_\_\_\_$ b$.$ For processes approaching six sigma, are C charts recommended? Yes $\_\_\_\_$; No$\_\_\_\_\_$ c$.$ C charts are based on the Binomial distribution: Yes $\_\_\_\_$; No$\_\_\_\_\_$ d$.$ Control charts are always considered to be normal: Yes $\_\_\_\_$; No$\_\_\_\_\_$ e$.$ Cpk can be $>$ Cp: Yes $\_\_\_\_$; No$\_\_\_\_\_$ f$.$ Cpk $<0$ indicates that the process mean is within the specification limits: Yes $\_\_\_\_$; No$\_\_\_\_\_$ g$.$ If there is no process average shift from Specification Nominal, then Cp $=$ Cpk: Yes $\_\_\_\_$; No$\_\_\_\_\_$ h$.$ For $2-$sided specifications and a centered process, Cpk $=$ Z$/6$: Yes $\_\_\_\_$; No$\_\_\_\_\_$ i$.$ The main difference between P charts and nP charts is the sample size, n: Yes $\_\_\_\_$; No$\_\_\_\_\_$ j$.$ A difference between C and U charts is that one uses the Binomial Distribution: Yes $\_\_\_\_$; No$\_\_\_\_\_$ k$.$ Moving range charts are considered to use a sample size $=8$: Yes $\_\_\_\_$; No$\_\_\_\_\_$
