Suppose that you work for a company that manufactures parts for use in the aerospace industry where the dimensions of parts must be extremely close to their designed specifications (so very little variation). If the length of a particular part may be used as long as the maximum variance is 0.0004, which of the following pairs of hypotheses would you recommend for the appropriate hypothesis test in this case? A. H subscript O colon space sigma less or equal than 0.0004 H subscript A colon space sigma greater than 0.0004 B. H subscript O colon space sigma greater or equal than 0.0004 H subscript A colon space sigma less than 0.0004 C. H subscript O colon space sigma equals 0.0004 H subscript A colon space sigma not equal to 0.0004
