Correct answer: B, C, D, E

Explanation

Option B is correct as it states that the process is assumed to follow a Normal distribution, which is a common assumption in capability analysis. Option C is accurate because it mentions the Mean of the process moving range specifically as 1.78. Option D is correct since it notes the use of subgroups in the analysis, which is typical for such evaluations. Option E is also true as it indicates that most values fall outside the established tolerances, highlighting a potential issue. Option A is incorrect because it claims the process is out of control, which is not supported by the other correct statements.
