The settled companies -competitors- tend to have a preference and market share obtained through years of operations which is a threat for a new company that is looking for attracting consumers.
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.

<u>b. Prototyping</u> refers to the process of developing a working replica of the system or some aspect of the system.
<u>Explanation</u>:
A prototype is a sample used by the system analysts or users to evaluate the new design or build to determine its precision. A prototype is a trial product or software that is widely used in software programming and electronics.
The accuracy of the newly developed product can be checked with the help of prototype. Prototype is the replica of the real product. It helps in correcting design error before its production. Consumer gets easily attracted by seeing the prototype before the release of the original product.
