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:
$16,700
Explanation:
The computation of the ending balance in the allowance for doubtful account is shown below:
= Unadjusted credit balance + Net credit sales × estimated bad debt percentage
= $4,100 + $210,000 × 6%
= $4,100 + $12,600
= $16,700
We simply added the unadjsuted credit balance and estimated amount after considered the estimated bad debt percentage
Answer:
Dr Cash $825
Cr Sales Returns and Allowances $800
Cr Sales Discounts $25
Explanation:
Preparation of the journal entry that Concord Company make upon receipt of the check
Dr Cash $825
($800+$25)
Cr Sales Returns and Allowances $800
Cr Sales Discounts $25
(To record receipt of the check)
Sales discount=(Sales Price -Sales return) × 1%
Sales discount=($3300 - $800) × 1% = $25
