In order for a new drug to be sold on the market, the variance of the active ingredient in each dose should be 0.02mg. A random sample of 12 tablets with a dosage strength of 56.02mg is taken. The variance of the active ingredient from this sample is found to be 0.0055. Does the data suggests at α=0.05 that the variance of the drug in the tablets is less than the desired amount? Assume the population is normally distributed. Step 1: State the null and alternative hypotheses. Round to four decimal places when necessary.   Step 2: Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer to three decimal places.   Step 3:  Determine the value of the test statistic. Round your answer to three decimal places.   Step 4:  Make the decision and conclusion

In order for a new drug to be sold on the market, the variance of the active ingredient in each dose should be 0.02mg. A random sample of 12 tablets with a dosage strength of 56.02mg is taken. The variance of the active ingredient from this sample is found to be 0.0055. Does the data suggests at α=0.05 that the variance of the drug in the tablets is less than the desired amount? Assume the population is normally distributed.

Step 1: State the null and alternative hypotheses. Round to four decimal places when necessary.
 
Step 2: Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer to three decimal places.
