Dogs are inbred for such desirable characteristics as color; but an unfortunate by-product of such inbreeding can be the emergence of characteristics such as deafness. A 1992 study of bull terriers (by Strain and others, as reported in The Veterinary Journal) found the following:
(i) |
50% of the studied bull terriers are white. |
(ii) |
11% of the studied bull terriers are deaf. |
(iii) |
20% of the white bull terriers are deaf. |
Based on the results of this study is "being white" independent of "being deaf"?
A. No, since .50 is not equal to .20.
B. No, since .50 * .11 is not equal to .20.
C. No, since .11 is not equal to .20.
D. Yes, since .50 * .11 is not equal to .20.
E. Yes, since .11 is not equal to .20.
Option-B) No, since .50 * .11 is not equal to .20.
Because if A and B are independent events then P(A and B) = P(A) * P(B)

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
