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:
Margin of safety= $12,000
Explanation:
Giving the following information:
Moe's Pizza Shop sells a large pizza for $12.00. Unit variable expenses total $8.00. The breakeven sales in units are 7,000 and budgeted sales in units are 8,000
To calculate the margin of safety in dollars, we need to use the following formula:
Margin of safety= (current sales level - break-even point)
Margin of safety= (8,000*12) - (7,000*12)= $12,000
Answer:
Payment to suppliers was $ 17,100
Credit sales was $37,200
Explanation:
