5. The manufacturer of an antibiotic must ensure that each 5 mL dose contains 250 mg of the active ingredient. It is also essential that the variance of the amounts of active ingredient per dose be less than 0.1. For testing purposes, a random sample of 96 doses is taken, and the variance of the amounts of active ingredient per dose in the sample is found to be 0.09. Does this evidence support the claim that the variance is within...
