Edit question

A physician wants to know if the number of male esophageal cancer patients diagnosed with multiple primary tumors differs from the proportion of female esophageal cancer patients with the same diagnosis. She selects random samples of 60 male and 40 female esophageal cancer patients and records the number in each sample diagnosed with multiple primary tumors. 40 men and 10 women with multiple primary tumors are identified.

What is the null hypothesis for this study?

If the tabulated critical value of the chi-square statistic for the 5% level of significance is 3.84, what is the most appropriate conclusion that can be drawn from this study?

The proportion of male esophageal cancer patients diagnosed with multiple primary tumors differs from the proportion of female esophageal cancer patients diagnosed with such tumors (p<0.05).

The proportion of male esophageal cancer patients diagnosed with multiple primary tumors does not differ from the proportion of female esophageal cancer patients diagnosed with such tumors (p>0.05).

It is 95% certain that the proportion of male esophageal cancer patients diagnosed with multiple primary tumors equals the proportion of female esophageal cancer patients diagnosed with such tumors.

The investigator can be 95% certain that more men than women have esophageal cancer.

Which of the following statements is an accurate interpretation of the p-value associated with the study conclusion?

The observed difference in sample frequencies is likely to be due to random chance.

The probability of obtaining the given sample results by random chance is less than 5%.

The sample sizes are too small to detect a significant difference in frequency.

The investigator can be certain that the proportion of men diagnosed with multiple primary tumors differs from the proportion of women with the same diagnosis.

The proportion of male esophageal cancer patients with multiple primary tumors is greater than that of female esophageal cancer patients with such tumors.

An association exists between gender and the presence of multiple primary tumors.

The proportion of men with esophageal cancer differs from that of women esophageal cancer.

The proportion of male esophageal cancer patients diagnosed with multiple primary tumors does not differ from that of female esophageal cancer patients diagnosed with multiple primary tumors.

The calculated value of the test statistic is:

0.65

16.67

In 2019, Bonita Enterprises issued, at par, 60 $1,000, 8% bonds, each convertible into 100 shares of common stock. Bonita had revenues of $20,500 and expenses other than interest and taxes of $6,700 for 2020. (Assume that the tax rate is 20%.) Throughout 2020, 2,200 shares of common stock were outstanding; none of the bonds was converted or redeemed.

(a) Compute diluted earnings per share for 2020. (Round answer to 2 decimal places, e.g. $2.55.)

(b) Assume the same facts as those assumed for part (a), except that the 60 bonds were issued on September 1, 2020 (rather than in 2019), and none have been converted or redeemed. Compute diluted earnings per share for 2020. (Round answer to 2 decimal places, e.g. $2.55.)

(c) Assume the same facts as assumed for part (a), except that 20 of the 60 bonds were actually converted on July 1, 2020. Compute diluted earnings per share for 2020. (Round answer to 2 decimal places, e.g. $2.55.)

There is a market operating for two periods. In the first period, there is only an incumbent firm, and an entrant may enter in the second period. The demand function each period is p = 20 − Q, where Q is the total quantity in the market. The per period cost function of each firm is c(q) = 9 + 4q. There is no discounting. Firms choose quantities.

(a) Find the monopoly outcome with these demand and cost functions.
(b) Because of some technological constraint, the incumbent cannot choose different quantitie in the two periods: qI = qI = qI . The entrant observes the incumbent’s quantity qI and decides if to enter and, if yes, how much to produce. Find the optimal choice of the entrant for any q.
(c) Suppose that the entrant will enter. Find the optimal quantity of the incumbent.
(d) Suppose now that the entrant will enter only if it makes positive profits. Find the subgame-perfect Nash equilibrium.

Design and implement class Rectangle to represent a rectangle object. The class defines the following attributes (variables) and methods:

1. Two Class variables of type double named height and width to represent the height and width of the rectangle. Set their default values to 0 in the default constructor.
2. A non-argument constructor method to create a default rectangle.
3. Another constructor method to create a rectangle with user-specified height and width.
4. Method getArea() that returns the area.
5. Method getPerimeter() that returns the perimeter.
6. Method getHeight() that returns the height.
7. Method getWidth() that returns the width.

Now design and implement a test program to create two rectangle objects: one with default height and width, and the second is 5 units high and 6 units wide. Next, test the class methods on each object to print the information as shown below.

Sample run:

First object:

Height:     1 unit

Width:      1 unit

Area:       1 unit

Perimeter: 4 units

Second object:

Height:     5 unit

Width:      6 unit

Area:       30 units

Perimeter: 22 units

Create a module to calculate the amount of royalties that Parker Schnabel must pay Tony Beets at the end of the gold mining season based on the following contractual agreement. When the amount of gold mined is 3000 ounces or less the rate is 15% of the gold value. This lower royalty rate is stored in a variable named lowerRate. When the amount of gold mined is greater than 3000 ounces the royalty rate is 20%. This higher rate is stored in a variable named goldRushRate and is applied only to the amount over 3000 ounces. The price of gold is currently $1200.00. This amount is stored in a variable defined as priceGold. The number of ounces mined is stored in a variable integer ouncesMined. You should ask Parker to input the number of ounces that he mined this season and print out “Based on x ounces mined, you paid y in royalties.”  You will need to multiply the ounces of gold mined by the price by the royalty rate to produce the proper royalties.

A010) One of the most active (and best studied) earthquake-prone areas is the San Andreas transform fault that forms a plate boundary between the North American Plate and the Pacific Plate. Turn on the San Andreas Major Ruptures folder to see rupture extents for three major earthquakes that have affected the San Andreas– Fort Tejon (1857, Mag. 7.9), San Francisco (1906, Mag. 7.8), and Loma Prieta (1989, Mag. 6.9). Also, in the Layers panel, turn on Gallery > Earthquakes.
   
Plate Boundary Earthquakes - San Andreas Fault, Wallace Creek, CA. What is the sense of offset along the San Andreas Fault? (i.e., Walk along either segment of Wallace Creek toward the fault. At the fault, determine the direction you turn to find the offset segment of the stream across the fault.)

A011) Plate Boundary Earthquakes - San Andreas Fault, Wallace Creek, CA. Use the Ruler tool to determine the distance (m) that Wallace Creek has been offset by recent motion along the San Andreas Fault (measure between the Problem 11 placemarks).

A012) Plate Boundary Earthquakes - San Andreas Fault, Wallace Creek, CA. Assuming that slip accumulates along the fault at about 6 cm/yr, how many years might it have taken to accumulate the slip that was released to produce the observed offset of the stream?

A015) Plate Boundary Earthquakes - San Andreas Fault, CA. Keep the San Andreas Major Ruptures folder turned on to show the extents of segments of the San Andreas Fault that have slipped during major seismic events. Using seismic gap analysis (where segments of a fault that have not recently slipped form "gaps" of accumulating strain transferred from adjacent slipped fault segments that highlight areas of greater potential for a "seismic" event), which placemark highlights a segment of the San Andreas Fault that has a high risk for an earthquake?
