1. This vitamin is involved with the metabolism of carbohydrates, fats and proteins. Rarely is there a deficiency of this vitamin because as the name suggests it is "widespread" in the food supply.

   		Biotin
   		Vitamin K
   		Folate
   		Pantothenic acid

2. Which of the following is not one of the functions of vitamin C?

   		Protects against infections
   		Involved in production and maintenance of collagen
   		Is a component of insulin
   		Promotes the absorption of iron

3. The treatment to this deficiency disease was accidentally discovered when the discarded brown coat of rice was given to chickens as scraps and then the attendant noticed the chickens did not walk stiff and weak following this diet. Alcoholics' staggering gait and jerky eye movements are the result of not being able to absorb the vitamin; usually a shot of this vitamin is given to those in rehabilitation programs. It is:

   		Thiamin B1
   		Riboflavin B2
   		Ascorbic acid C
   		Vitamin K

4. Sulfur, a mineral that forms bridges between amino acids and provides the rigid shape of nails and hair, is adequate in a diet that contains sufficient:

   		Fat
   		Protein
   		Carbohydrate
   		Vitamins

5. Which of the following minerals is part of the digestive acid that maintains the low pH of the stomach?

   		Heme
   		Chromium
   		Copper
   		Chloride

6. The following minerals are all involved in red blood cell (RBC) formation and utilization except:

   		Zinc
   		Copper
   		Iron
   		Fluoride

In a study to evaluate drug efficacy, the manufacturer of a new type of generic drug for treating a
disease wants to investigate the effectiveness of this generic drug as compared to the traditional
brand name drug, At the present time, the brand name drug is the only approved treatment for the
disease. Patients diagnosed with the disease have low concentration of a specific factor in their
blood. Treatment with the brand name drug will result in an increase in the concentration of the
specific factor in the blood. An experiment is conducted in which 10 patients currently with the
disease are randomly assigned to receive either the generic drug or the brand name drug for a
period of 9 months. After 9 months have elapsed, a measure of the concentration level of the
specific factor in the blood is obtained for each patient. The results are shown in Table Q1.

(a) At a 5 % level of significance, apply a two-sample t test to determine whether there is
any difference in the concentration levels between brand name drug and generic drug.
Comment on the results.

(b) Construct a 90 % confidence interval for the difference in the mean concentration
levels between brand name drug and generic drug.

(c) Suppose now the manufacturer wishes to demonstrate whether the concentration level
of brand name drug exceeds that of generic drug by more than 1, apply a two-sample t
test to analyze the problem based on 1 % level of significance.

Read and print parallel array - How can this be made to read parallel arrays and then print them?

The program presented here is intended to read from the text file and build parallel arrays. Then it will print as shown. The first line will not be stored in the array. The second line will be stored in firstArray[] and the third line will then be stored in secondArray[] and the arrays will repeat until the file is read.

infile.open(filname.c_str());
getline(infile, line);

infile >> line; // first line

Problem(1) (a) Consider the (random) experiment of throwing THREE coins together. Let S denote the sample space. List the elements in S.

(b) If HEAD comes up, you win $2 dollars; you lose $1 dollar if TAIL shows up. Let X be the random variable that corresponds to the money you win (a positive value) or lose (a negative value). What are the values that the random variable X takes?

(c) Suppose that the coin is made and thrown fairly. Find P[X = 2].

(d) Find E[X].

(e) Find E[X2 ].

(f) Find V ar[X].

An engineering students designs and builds a capacitor from some scrap iron. One piece of iron is a square with side lengths of 10 cm, while the other piece is a rectangle that is 20 cm long and 10 cm wide. The student knows they can keep the plates separated by a distance of 1.2 micrometers.

a. What is the capacitance of this setup?

b. If the capacitor is fully charged using a 1.5 V battery, how much charge is built up on the plates?

c. How much energy is stored?

d. After performing the experiment, the student inserts a dielectric with a k value of 1.2. What values would this change?

Assume the government wants to increase GDP and income Y. It has $100 million to use. Explain why spending it on roads and bridges (government spending G) will increase Y more or less than if it used the money on transfer payments (R) such as welfare payments. You must refer to the multiplier and mathematically why one policy would be different from the other. Explain why one policy would work better than the other.
