Given a recent outbreak of illness caused by E. coli bacteria, the mayor in a large city is concerned that some of his restaurant inspectors are not consistent with their evaluations of a restaurant’s cleanliness. In order to investigate this possibility, the mayor has five restaurant inspectors grade (scale of 0 to 100) the cleanliness of three restaurants. The results are shown in the accompanying table. (You may find it useful to reference the q table.)

Inspector	Restaurant
Inspector	1	2	3
1	72	54	84
2	68	55	85
3	73	59	80
4	69	60	82
5	75	56	84 If the average grades differ by restaurant, use Tukey’s HSD method at the 5% significance level to determine which averages differ. (If the exact value for n_T − c is not found in the table, use the average of corresponding upper & lower studentized range values. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)

Researchers grew populations of identical Escherichia coli (E. coli) bacteria in a growth medium that contained a low concentration of glucose and a high concentration of citrate, a substance that is not typically consumed by E. coli. For thousands of generations, the bacteria used only glucose as an energy source and grew relatively slowly (and to a low density because of the low concentration of glucose). After about 30,000 generations, one population emerged that began to rapidly grow to a...

The bacteria E. Coli doubles in a little over 20 minutes in good lab conditions. (For purposes of this exercise, we will assume it takes exactly 20 minutes.) a) Write a difference equation that models the growth of an E.

What is the solution to this equation and initial condition? b) How would the equation change if the...
