The researcher wants to investigate whether carpet makes a difference in the mean bacterial concentration in air. the null and alternative hypotheses would be:
H0: The mean of the carpeted rooms = the mean of the uncarpeted rooms
Ha: The mean of the carpeted rooms ≠ the mean of the uncarpeted rooms
The attention of bacteria majorly depends on the awareness of inoculum, incubating temperature, and the metabolic country of inoculated pressure used. The bacterial concentration suspended in growth media may be calculated.
In idea, you could listen to cells through filtration or centrifugation, but likely no greater than a hundredfold. for your case, you're asking to concentrate by 10,000 fold. So you sincerely might want to develop denser cultures of cells. You can centrifuge your modern broth and resuspend the pallet in a clear broth.
In microbiology, the minimal inhibitory attention (MIC) is the lowest concentration of a chemical, generally a drug, which prevents the visible boom of a bacterium or bacteria.

Answer:
Option c) how a consumer might trade off different levels of consumption of each of two goods, while staying at the same utility level.
Explanation:
This is the very definition of an indifference curve. The points in an indifference curve are the combinations of the quantities (level of consumption) of two different goods which will produce the very same utility to the consumer. The consumer will perceive any of those combinations as having the same utility for him.
For example, a usual graph of various indifference curves will look like the graph attached.
In this graph the combination of 2 pairs of shoes and 15 pants will be perceived as having the same utility as the combination of 5 pairs of shoes and 4 pants. Both are combinations in the same indifference curve, the green one, and the utility of any combination lying in that green curve will be rated the same: u = 1.
