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 correct answer is True.
Explanation:
A good supply chain aims to maximize the profitability of the company while trying to provide the best service in order to obtain a high degree of customer satisfaction. That is why, when planning the design, it must be customer oriented and not only focused on the company.
Steps prior to the design of the supply chain
When designing the supply chain, there are several points to consider in order to obtain a coherent and functional design.
- The members that become part of the chain. The first thing to be fixed are the members that are part of the chain, since this will be the guide to go through the rest of the steps. Within this, a subdivision could be carried out, but it is worth mentioning that an agent can be a principal or support agent jointly depending on the work to be done at each moment:
- Principal. They are the ones that provide direct value to the product or service.
- Of support. They are those members whose function is to provide information or resources to the main members, such as banks.
- Structure that forms the chain, that is, all the phases through which a product / service passes in order to be marketed as such. At this point we must try to be as meticulous as possible and always add as much as possible all the phases that are involved, both in manufacturing and in supply.
- Processes and flows that are carried out in each of the structures mentioned above.

Explanation:
Answer:
Fixed Overheads Spending Variance = $5,000 Unfavorable(U).
Fixed Overheads Spending Variance = $20,000 Favorable (F).
Explanation:
Fixed Overheads Spending Variance = Actual Fixed Overheads - Budgeted Fixed Overheads
= $305,000 - $300,000
= $5,000 Unfavorable(U).
Fixed Overheads Spending Variance = Fixed Overheads at Actual Production - Budgeted Fixed Overheads
= ($5.00 × 64,000) - $300,000
= $320,000 - $300,000
= $20,000 Favorable (F)
