Standard requirements for a certain drug stipulate that the variance in drug weights must not exceed 0.03 grams (squared). A sample of five units provided the sample data as follows: 0.1 0.3 0.5 0.6 0.25

Required:

a)

Use hypotheses test to determine whether the variance in the drug weights meets the standard requirements. Use = 0.01 and show all the hypothesis test steps. (
