**Using SPSS softwareCompany officials are concerned about the length of time a particular drug retains its potency. A random sample of 10 bottles of the product is drawn from current production and analyzed for potency. A second random sample is obtained, stored for 1 year, and then analyzed. The readings obtained are as follows: Current 10.2 10.5 10.3 10.8 9.8 10.6 10.7 10.2 10.0 10.6 After 1 Year 9.8 9.6 10.1 10.2 10.1 9.7 9.5 9.6 9.8 9.9 Using a six-step test with the P-value approach (with = 0.05) and the appropriate SPSS output, test the hypothesis that the mean potency of this drug is lower after 1 year of storage. Check any necessary assumptions. If you reject the null hypothesis, you should interpret a 90% confidence interval for the actual difference. If you fail to reject the null hypothesis, you should explain why it is not necessary to use a confidence interval to estimate the actual difference. Include only the appropriate SPSS output with your answer
