The numerical course grades in a statistics course can be
approximated by a normal model with a mean of 70 and a standard
deviation of 10. The professor must convert the numerical grades to
letter grades. She decides that she wants 10% A's, 30% B's, 40%
C's, 15% D's, and 5% F's.
a. What is the cutoff for an A grade?
(Use 2 decimal places.) (Draw a picture!.)
a. What is the cutoff for an B grade?
(Use 2 decimal...
Develop a wall chart that compare and contrast the
prototype drug from each antiepileptic drugs with other drug within
that class, discuss how drugs within each class compare to each
other and with drugs in other classification
Construct an original numerical example of a
Ricardian model in which one country has an absolute advantage in
the production of both goods.
Make an assumption about the amount of labor resource available
in each country, then draw each country’s PPF.
Will trade be mutually advantageous in your example? If not,
why not? If trade is mutually advantageous, give an example of one
international terms of trade that would make trade mutually
advantageous.
1. Consider the following numerical example of the IS-LM model:
25 C = 100 + 0.3YD I = 150 + 0.2Y - 1000i T = 100 G = 200 i = .01
(M/P)s = 1200 (M/P)d = 2Y - 4000i a. Find the equation for
aggregate demand (Y). b. Derive the IS relation. c. Derive the LM
relation if the central bank sets an interest rate of 1%. d. Solve
for the equilibrium values of output, interest rate, C and...
Use the following data to develop a quadratic model to predict
y from x. Develop a simple regression model from
the data and compare the results of the two models. Does the
quadratic model seem to provide any better predictability? Why or
why not?

Develop a conceptual data model for the following scenario:
The data model should consist of the usual 5 components: E-R
diagram, Entity Types (including entity type identifiers),
assumptions, additional constraints, and limitations:
It is desired to develop a shop database for a shop of different
classes of products.
A shop sells different classes of products to customers. For
each class, it is required to keep the following information: class
identification number (class-id) and class name. Each class has one
