16. A pharmaceutical manufacturer does a chemical analysis to check the potency of products. The standard release potency for cephalothin crystals is 910. An assay of 16 lots gives the following potency data:

897 914 913 906 916 918 905 921 918 906 895 893 908 906 907 901

Is there significant evidence at the 5% level that the mean potency is not equal to the standard release potency?

using a TI-83 plus

Expert Solution

Let denotes the mean potency.

To find critical value, we need to use TI 83 plus calculator. Formula : invT(0.975,15)

To value p-value using TI 83 plus, formula :2* tcdf(-E99, -1.061152,15)

In problem 23P in Chapter 4 of Quantitative Chemical Analysis the answer says that the standard deviations for the two measurement methods are different. But if I apply the the F test I find that the standard deviations for the two measurement methods are not statistically different at the 95 % confidence level for the cases of both rainwater and drinking water. For rainwater the value of Fcalc = 2.56 and the F table gives 4.53 so the standard deviations...
