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:
A. limited details of offer
Explanation:
The offer is strong as it reaches only the persons that are fans and will be more interested in this event. The only particular reason for this offer to fail is that the message won't contain enough information about the event and this will lose the attention of the fans.
Answer:
The correct answer is option D.
Explanation:
An increase in the cost of fishing will lead to a decrease in the supply of fishes. This happens because the suppliers will be able to supply less at the same cost.
So the supply curve will move to the left. This leftward shift in the supply curve will cause the equilibrium price to increase and the equilibrium quantity to decrease.
All the other options would have caused the equilibrium quantity to increase either through increased demand or increased supply.
