Answer: Last Option is correct.
Step-by-step explanation:
Since we have given that
Total number of population = 25000
Percent of sample of Jason = 0.24%
Percent of sample of Yolanda's = 0.32%
So, Number of population according to Jason's sample is given by
Number of population according to Yolanda's sample is given by
Both the sample can be used to make inferences about the population
Hence, Last Option is correct.
Answer:
The correct answer is NO. The best price to be charged is $3.75
Step-by-step explanation:
Demand equation is given by Q = 30 - 4P, where Q is the quantity of necklaces demanded and P is the price of the necklace.
⇒ 4P = 30 - Q
⇒ P =
The current price of the necklace $10.
Revenue function is given by R = P × Q = × ( 30Q -
)
To maximize the revenue function we differentiate the function with respect to Q and equate it to zero.
=
× ( 30 - 2Q) = 0
⇒ Q = 15.
The second order derivative is negative showing that the value of Q is maximum.
Therefore P at Q = 15 is $3.75.
Thus to maximize revenue the price should be $3.75.
