The complete question is as follows:
The admission directory of Big City University has a novel idea. He proposed using the IQ scores of current students as a marketing tool. The university agrees to provide him with enough money to administer IQ tests to 50 students. So the director gives the IQ test to an SRS of 50 of the university’s 5000 freshman. The mean IQ score for the sample is xbar=112. The IQ test he administered is known to have a σ of 15. What is the 95% Confidence Interval about the mean? What can the director say about the mean score of the population of all 5000 freshman?
Answer: The 95% confidence interval about the mean is
.
The director can say that he is 95% confident that the mean IQ score of the 5000 freshmen lies between 107.84 and 116.16.
We follow these steps to arrive at the answer:
Since the population standard deviation of the IQ test is known, we can use the Z scores to find the confidence interval.
The formula for the confidence interval about the mean is:

In the equation above, X bar is known as the point estimate and the second term is known as Margin of Error.
The Critical Value of Z at the 95% confidence level is 1.96.
Substituting the values in the question in the equation above we have,



Answer:
D : All options are correct
Explanation:
- The marginal buyer is the essence of demand curve while marginal seller is essence of supply curve.
- @ Q = 500 units, Selling Price is set at SP = $35
- @ Q = 500 units, Buying Price is set at BP = $40
- Since, SP ≠ BP our equilibrium price would be $ 37.5 assuming the price elasticity of demand and supply are equal. In any case the equilibrium price would lie in between [ 35 , 40 ] such that to prevent a shortage of units in near future.
- Moreover, if the seller decides to sell at price $35 then he must sell goods greater than 500 units to reach the equilibrium profits. However, it could also lead to excess of units or surplus.
- We see that from selling the goods at SP = $35 while the buyer is willing to pay BP = $40 for 500 goods, the seller would be under-profiting and would be earning $5*500 = $2,500 less than he would at equilibrium price of $40 and selling units greater than 500. Hence, 500 goods is not an efficient quantity of goods.
