Answer:
675 samples
752 samples
Step-by-step explanation:
Given that :
α = 90%
E = 0.03
Previous estimate (p) = 0.34
Estimated sample proportion (n)
n = p *q * (Zcritical /E)
Zcritical = α/2 = (1 - 0.9) /2 = 0.1 / 2 = 0.05
Z0.05 = 1.645 ( Z probability calculator)
q = 1 - p = 1 - 0.34 = 0.66
n = 0.34 * 0.66 * (1.645/0.03)^2
n = 674.70
n = 675
B.) without prior estimate given ;
p and q should have equal probability
Hence ;
p = 0.5 ; q = 0.5
n = 0.5 * 0.5 * (1.645/0.03)^2
n = 751.67361
n = 752
To determine the sample size for the research, a mathematical calculation is required, considering the level of confidence, the desired margin of error, and, if available, a previous estimate. For a 90% confidence level, two calculations are made based on an assumed proportion—first using the existing estimate of 0.34, and second with no prior estimate (commonly taken as 0.5).
The researcher is trying to determine the sample size required for a study on high-speed Internet access. The sample size can be calculated based on the level of confidence desired and the desired margin of error. In this case, (a) she is using a previous estimate of 0.34 and (b) she does not use any prior estimates.
For the calculation, we can use the formula for sample size in hypothesis testing for a population proportion:
n = (Z^2 * p * (1-p)) / E^2
Where:
For a 90% confidence level, the corresponding z-score is approximately 1.645. Now we can plug in the numbers.
(a) If she uses a previous estimate of 0.34, the calculation would be:
n = (1.645^2 * 0.34 * 0.66) / (0.03)^2
You will need to round up to the nearest whole number as you cannot have a part of a participant.
(b) If no previous estimate is used, it is common practice to use 0.5 as this will provide the maximum variance and, therefore, the largest sample size. The calculation would be:
n = (1.645^2 * 0.5 * 0.5) / (0.03)^2
Again, round up to the next whole number. Insert the results for these calculations to your answer.

Answer:
4000grams in each bag
Step-by-step explanation:
Assume he put x amount of clay into each bag, he then put 6x into 6 bags.(since the question didn’t mention, I assume he put every clay he has into the bags)
6x=24kg
x=4kg
Since the question is asking for grams not kilograms:
4kg=4000g

the sole proprietor is not liable under any circumstance
the sole proprietor is covered by a Small Business Administration insurance policy
the sole proprietor is liable only for a small fraction of any damages
Answer:
the sole proprietor is personally liable for damages the injured woman is awarded by the courts.
Step-by-step explanation:
In a sole proprietorship, the owner is personally liable for any damages awarded by the court in the event of a lawsuit. They are not typically covered by small business insurance, and their liability is not limited.
Based on the question, the owner in a sole proprietorship is personally liable for any damages that are awarded by the court. This means that if a customer slipped and fell in her store and sued the owner, the sole proprietor- the business owner, would be held responsible for paying any damages. The liability of the sole proprietor emanates from the fact that in this type of business entity, there is no legal distinction between the owner and the business. This means all the debts and liabilities of the business are considered to be those of the owner. Thus, under normal circumstances, a sole proprietor is not covered by a Small Business Administration insurance policy, and their liability is not limited to a small fraction of the damages.
