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...
