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:
The answer would be neutrality of money theory
Explanation:
The neutrality of money theory claims that changes in the money supply affect the prices of goods, services, and wages but not overall economic productivity. Many of today's economists believe the theory is still applicable, at least over the long run.
I think the answer is C but i could be wrong
Answer:
166.25 hours
Explanation:
It take 25 hours if the production is going at 100% capacity, but the production is only going at 67%, therefore, 33% of the capacity is under utilized. It takes 8.25 more hours to finish the unit since the capacity is only at 67%. Finally, it takes 25+8.25 hours to finish a single product, hence taking 166.25 hours for 5 units.
We do this like this:
--> 25 ------ 100
--> X ------ 33
--> 33*25 = 100*X
--> 825/100
--> X=8.25
Hope this clears everything. Thankyou.
