The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
Answer:
c. $33.33 per housekeeping hour
Explanation:
The housekeeping department's activity rate is how much each housekeeping hour costs.
This question can be solved by a simple rule of three.
27000 hours cost $900000. How much does 1 hour cost?
27,000 hours - $900,000.
1 hour - $x.
So the correct answer is:
c. $33.33 per housekeeping hour
Answer:
Using LIFO:
TOTAL Sales : $19,875,500
COGS = $11,021,250
GROSS PROFIT = $8,853,750

Answer:
About the Lagrangian method,
We can use it to solve both consumer's utility maximization and firm's cost minimization problems.
Explanation:
Lagrangian method is a mathematical strategy for finding the maxima and the minima of a function subject to equality constraints. Equality constraints mean that one or more equations have to be satisfied exactly by the chosen values of the variables. Named after the mathematician, Joseph-Louis Lagrange, the basic idea behind the Lagrangian method is to convert a constrained problem into a Lagrangian function.
Answer:
Letter E is correct. <em>Their share of the cost is hig</em>h.
Explanation:
Price sensitivity is characterized by consumer behavior in relation to the price of a product or service.
The degree of price sensitivity can be measured using the price elasticity of demand, which is the study of the percentage change in the amount of demand for a good or service divided by the percentage change in price.
Some variables may affect consumer behavior, price sensitivity may be higher when there are many substitute products and lower when the consumer values a higher quality good and <u>when its profitability is higher compared to the total cost of the product.
