Managerial Economics Question
1. The Poster Bed Company believes that its industry can best be classified as monopolistically competitive. An analysis of the demand for its canopy bed has resulted in the following estimated demand function for the bed:
P= 1760 - 12Q
The cost analysis department has estimated the total cost function for the poster bed as
TC = (1/3)Q^3 - 15Q^2 + 5Q + 24,000
A) Calculate the level of output that should be produced to maximize short-run profits.
B) What price should be charged?
C. Compute total profits at his price-output level.
D) Compute the point price elasticity of demand at the profit-maximizing level of output.
E) What level of fixed costs is the firm experiencing on its bed production?
F) What is the impact of a $5,000 increase in the level of fixed costs on the price charged, output produced, and profit generated?

Substantial uncertainty exists regarding the causal effect of health insurance on the utilization of care. Most studies cannot determine whether the large differences in healthcare utilization between the insured and the uninsured are due to insurance status or to other unobserved differences between the two groups. In this paper, we exploit a sharp change in insurance coverage rates that results from young adults “aging out” of their parents’ insurance plans to estimate the effect of insurance coverage on the utilization of emergency department (ED) and inpatient services. [In the US, children are eligible for insurance coverage through their parents’ insurance only up to their 23rd birthday, at which point they lose eligibility.] Using the National Health Interview Survey (NHIS) and a census of emergency department records and hospital discharge records from seven states, we find that aging out results in an abrupt 5 to 8 percentage point reduction in the probability of having health insurance. We find that not having insurance leads to a 40 percent reduction in ED visits and a 61 percent reduction in inpatient hospital admissions.

Determining the Speed of Sound Name Abstract; Include instead of these lines the objectives of the lab (what you investigated), the short description of how you did it and the conclusions formulated based on the obtained results. It should be ½ to 1 page long. Picture of the experimental set up Observations Data Table 1: Calculation of sound wavelength Tuning fork frequency f (Hz ) Length, (water level to top of tube) L (m) Diameter of tube, d(m) λ(m) =4(L + 0.3d) Experimental v(m/s) = f λ Room Temperature, oC Calculations A. Calculate the theoretical speed of sound (v): v = 331.4 + 0.6T0C ( m/s) • 331.4 m/s is the speed of sound at 20oC • T0C is the temperature of air during testing measured in Celsius B. Calculate the percent error of your experimentally derived value: C. Describe what is sound. D. Explain the phenomenon based on which you were able to hear the amplified sound and to determine the speed of sound. You should include a picture or a sketch of the standing waves (the key concept you need to write about) inside the tube. Because this might require different printed or electronic resources, make sure you include the references. E. What is the physical concept behind the “pitch” of a sound and what is the SI unit for it? F. What is the physical concept behind “intensity” of a sound and what is the SI unit for it? G. What are possible sources of errors in this experiment?

ABSTRACT: The objective of this study was to test a variety of bush meat products sold by meat retailer. Police investigate the incident and seized the knife. There was a small piece of tissue adhering to the knife for further investigation. DNA was extracted from the meat sample and PCR done using Forward: L14841 (5'-AAAAAGCTTCCATCCAACATCTCAGCATGATGAAA-3') and Reverse: H15149 (5'-AAACTGCAGCCCCTCAGAATGATATTTGTCCTCA-3') primer. after that dna sequencing performed for identification of species. The resulted sequence aligned against Nucleotide blast and create phylogenetic tree to identify nearest species of suspect. We identify our suspect species matches with Ceratotherium simum. The White rhinoceros , which is illegal to sell on the commercial market, was detected.

A test of abstract reasoning is given to a random sample of students before and after they completed a formal logic course. The results are given below. Construct a 95% confidence interval for the mean difference in tests scores. Research has shown that the distribution of such differences is approximately normal. Interpret your result.

These questions are about an abstract data type for sets of integers. The representation used will be sorted lists without duplicates. To help answer the questions, the following pseudocode of merge-sort for lists may be useful. It is assumed head(x) and tail(x) return the head (first element) and tail (remaining elements) of a list, respectively, and a procedure is available for splitting a list into two lists of approximately equal size.
// returns sorted version of list x
mergesort(x):
if x is empty or tail(x)
is empty then return x
split x into lists x1
and x2
s1 = mergesort(x1)
s2 = mergesort(x2)
return merge(s2, s2)
// returns merge of sorted lists s1 and s2
merge(s1, s2):
if s1 is empty then return s2
if s2 is empty then return s1
if head(s1) < head(s2) then
h = head(s1)
s3 = merge(tail(s1),
s2)
add h to front of
s3
return s3
else
h = head(s2)
s3 = merge(s1,
tail(s2))
add h to front of
s3
return s3
(a) Describe an algorithm (preferably using pseudo-code) to
determine if a number n is an element of a set s (a sorted list
without duplicates) and give the worst case time complexity.
(b) Describe an algorithm to convert an arbitrary list of integers
(not necessarily sorted or free of duplicates) to a set (sorted and
without duplicates) and give the worst case time complexity.
(c) Describe an algorithm to compute the union of two sets and give
the worst case time complexity (the union of two sets is the set of
elements which are in either of the two sets).
(d) Describe an algorithm to compute the intersection of two sets
and give the worst case time complexity (the intersection of two
sets is the set of elements which are in both of the two sets).
(e) Briefly argue why this representation of sets is better than a
representation which uses arbitrary lists.
