1. Bisphenol A is a plasticizer widely used in polycarbonate
water bottles and liners in metal food cans. A plasticizer is a
chemical blended with plastic polymers to make the plastic softer
and more pliable. Out of health concerns, the U.S. Environmental
Protection Agency is currently considering tightening regulations
on bisphenol A use and lowering human exposure limits. a) Assuming
your blood serum is similar to water, what is the maximum
concentration of bisphenol A that could be present in...

"The most widely used stain in microbiology is the Gram
stain. Based on differences in the structure of the bacterial cell
wall, the Gram stain divides bacteria into two major groups:
Gram-positive and Gram-negative. Gram-positive cells have a thick
layer of peptidoglycan, a polymer made of amino acids and sugars,
in the cell wall. Crystal violet binds to peptidoglycan, rendering
the cell purple. Gram-negative cells also have peptidoglycan and
initially also stain purple. Since the peptidoglycan layer is much
thinner,...

The SAT is the most widely used college admission exam. (Most
community colleges do not require students to take this exam.) The
mean SAT math score varies by state and by year, so the value of µ
depends on the state and the year. But let’s assume that the shape
and spread of the distribution of individual SAT math scores in
each state is the same each year. More specifically, assume that
individual SAT math scores consistently have a normal...

Heat treating is often used to carburize metal parts, such as
gears. The thickness of the carburized layer is considered a
crucial feature of the gear and contributes to the overall
reliability of the part. Because of the critical nature of this
feature, two different lab tests are performed on each furnace
load. One test is run on a sample pin that accompanies each load.
The other test is a destructive test, where an actual part is
cross-sectioned. This test...
