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:
$6,900
Explanation:
When you use the incremental cost allocation method, you must rank cost activities and how they will be allocated. In this case, department 2 is the primary user, and therefore, rental costs must be allocated first to them. Rental costs will be allocated at a $25/hour rate.
Since department 1 is the next user, 100 hours will be allocated using the same rate as department 2, but the next 200 hours will be allocated at the lower $22/hour rate. Total rental cost allocation to department 1 = (100 x $25) + (200 x $22) = $2,500 + $4,400 = $6,900
Answer:
D) The extra energy benefits Patrick gets from another can are no longer worth the cost. MB/MC (S)
Explanation:
The optimal quantity for Patrick to consume is 5 cans of GreenCow.
This is the quantity where MARGINAL BENEFIT EQUALS MARGINAL COST. For all quantities up to the 5th, the marginal benefit is higher than the marginal cost. This means that Patrick's net benefit is increasing, and consuming all units up to this point make him better off.
If Patrick were to consume any more than 5 cans of GreenCow, the cost of each additional can would be higher than the additional benefit (because the marginal cost curve is higher than the marginal benefit curve). Consuming any cans beyond the 5th, therefore, makes him worse off.
