Health Law

In the United States, all medical malpractice law is litigated and resolved in one of two ways. Each state will choose which theory (only one theory is chosen to be used by each state) used to resolve all cases within their jurisdiction. The first is the theory of contributory negligence. In this theory, the original law (and ancient law derived from the Common law of England) states that, under this doctrine, if the patient contributed at all to the harm caused by the medical professional, then the patient was not entitled to any compensatory relief. In other words, no suit for damages would be allowed against the medical provider. This theory insisted that only a completely blameless patient should have recourse against a medical professional.

The second theory is the theory of comparative negligence. This is the more modern doctrine. Under comparative negligence all injured patients could still file a malpractice suit even if the patient contributed to the harm caused. Therefore, if a doctor was 50% at fault and the patient was 50% at fault, the patient could still recover 50% of the damages from the doctor.

Set forth two strengths and two weaknesses for each of these theories and choose which one you believe to be the most just and why.

According to Mars, Inc., 20% of all M&Ms produced are blue. One bag of 50 M&Ms represents the sample for this problem. The sample data can be used to perform a two-sided hypothesis test to test whether 20% of all M&Ms are blue.

In one bag of 50 M&Ms, there are 14 blue M&Ms. Use this data to test whether 20% of all M&Ms are blue.

Periodic Inventory by Three Methods

Pappa's Appliances uses the periodic inventory system. Details regarding the inventory of appliances at January 1, purchases invoices during the year, and the inventory count at December 31 are summarized as follows:

Required:

1. Determine the cost of the inventory on December 31 by the first-in, first-out method.

If the inventory of a particular model comprises one entire purchase plus a portion of another purchase acquired at a different unit cost, use a separate line for each purchase. If units are in inventory at two different costs, enter the units PURCHASED MOST RECENTLY first.

2. Determine the cost of the inventory on December 31 by the last-in, first-out method.

If the inventory of a particular model comprises one entire purchase plus a portion of another purchase acquired at a different unit cost, use a separate line for each purchase. If units are in inventory at two different costs, enter the OLDEST units first.

3. Determine the cost of the inventory on December 31 by the weighted average cost method.

4.   would be preferred for income tax purposes in periods of declining prices.

A certain tennis player makes a successful first serve 76​% of the time. Suppose the tennis player serves 50 times in a match.​ What's the probability that she makes at least 42 first​ serves?

ErdemS (ES) is a monopoly selling tickets for the football match of SileSpor. The demand for each ticket is P = 350 - Q. ES’s cost is $10,000 plus $50 per ticket. (i.e., C(Q)=10.000+50Q ).

a) What is the profit-maximizing price that ES will charge? How many tickets will be sold? What is ES’s profit for this match?

b) Next ES finds out that non-students (Type A) and students (Type B) have different demands:   Let P_A = 650 - 5Q_A stand for the demand function of Type A; and let P_B =350-3Q_B stand for the demand function of Type B. Suppose that ES utilizes price discrimination and asks different prices to each type.

What is the price charged to a non-student (Type A)? What is the price charged to a student (Type B)? How many of each type are on this match? What would ES’s profit be for this match?

Use the information to answer the following questions. • The Global Advertising Company has a marginal tax rate of 40%. • The company can raise debt at a 8% interest rate. • The last dividend paid by Global was $1.10. Global’s common stock is selling for $7.93 per share, and its expected growth rate in earnings and dividends is 4%. • Global plans to finance all capital expenditures with 20% debt and 80% equity.

What is the after-tax cost of debt for the company?

What is Global's cost of common stock if it can use retained earnings rather than issue new common stock?
