Suppose you are a chemist who is trying to synthesize a specific compound. You have been working with a new technique and you think that this process can turn 60% of the input compounds into the desired synthesized compound, and want to attempt the process enough times to get an estimate that is within .04 of the true proportion that is converted. How many times should you execute the process to get the desired precision
Answers
Answer:
The sample size 'n' = 576
576 times should you execute the process to get the desired precision
Step-by-step explanation:
Explanation :-
Step(i)
Given data the process can turn 60% of the input compounds into the desired synthesized compound.
Sample proportion ' p' = 60% = 0.60
Given data the estimate within 0.04 of the true proportion that is converted
The margin of error of the true population proportion
M.E = 0.04
Step(ii)
The margin of error of the true population proportion is determined by
on calculation, we get
squaring on both sides ,we get
n = 576
Final answer:-
The sample size 'n' = 576
576 times should you execute the process to get the desired precision

r = 5.7/2 = 2.85
h = 12
Volume of original design =1/3π(2.85)²(12)
= 32.49π
= 102.07.....
Linear scale factor = 1.5 = 3/2
Volumetric scale factor = (3/2)³ = 27/8
Volume of revised design = 102.07..... × 27/8

Answer:
Dr cash $65,000
Cr Notes payable $65,000
repayment:
Dr Notes payable $11,531
Dr interest expense $3,900
Cr Cash $15,431
Step-by-step explanation:
Upon the issuance of the notes,the cash received would be debited to cash account and the same amount credited to notes payable account.
The payment of $15,431 as annual repayment on the notes payable would be credited to cash account as an outflow of cash from the business while the notes payable and interest expense accounts would be debited with $11,531 and$3,900 respectively
