Chapter 9.3, Problem 19E
The article “Cellulose Acetate Microspheres Prepared by O/W Emulsification and Solvent Evaporation Method” (K. Soppinmath, A Kulkarni, et al., Journal of Microncapsulation, 2001:811–817) describes a study of the effects of the concentrations of polyvinyl alcohol (PVAL) and dichloromethane (DCM) on the encapsulation efficiency in a process that produces microspheres containing the drug ibuprofen. There were three concentrations of PVAL (measured in units of % w/v) and three of DCM (in ml.). The results presented in the following table are consistent with the means and standard deviations presented in the article.
- a. Construct an ANOVA table. You may give
ranges for the P-values. - b. Discuss the relationships among PVAL concentration, DCM concentration, and encapsulation efficiency.

Wing Foot knows that its stores will not show a profit unless they gross over $940,000 per year. Let A be the event that a new Wing Foot store grosses over $940,000 its first year. Let B be the event that a store grosses over $940,000 its second year. Wing Foot has an administrative policy of closing a new store if it does not show a profit in either of the first two years. Assume that the accounting office at Wing Foot provided the following information: 58% of all Wing Foot stores show a profit the first year; 72% of all Wing Foot store show a profit the second year (this includes stores that did not show a profit the first year); however, 86% of Wing Foot stores that showed a profit the first year also showed a profit the second year.
