For each sentence in the following passage, decide whether it is necessary to add quotation marks or cite a source. Explain your reasoning.

Many people have made money investing in real estate in the past couple of years. However, what goes up, comes back down (1). EZHomeBuilders, a corporation that builds luxury homes, announced that falling real estate values are causing them to scale back some projects and cancel others (2). After they announced this, shares of EZHomeBuilders fell 50 percent on the New York Stock Exchange, closing at $27.14 per share (3). Shares of other major builders fell as well (4).

My aunt, Shelly Maughn, who is a residential real estate broker, says she thinks the market will return to the way it was about a decade ago, with prices increasing more slowly (5). She also used to work in retail sales and sold furnishings and appliances for homes where she watched sales go up and down with the housing market (6). When business for home builders slowed, business slowed for us, she says (7).

I worked as an intern in Aunt Shelly’s real estate office last summer and I really enjoyed it (8). One day, I hope to become a residential real estate broker and investor even though real estate can be a challenging career (9).

06. Testing a new insect repellent. (Adapted from McClave, Benson, & Sincich, 12th edition, page 556). A study in the Journal of the American Mosquito Control Association (Mar. 1995) investigated whether a tent sprayed with a commercially available 1% permethrin formulation would protest people, both inside and outside the tent, against biting mosquitoes. Two canvas tents — one treated with permethrin, the other untreated — were position 25 meters apart on flat, dry ground in an area infested with mosquitoes. Eight people participated in the experiment, with four randomly assigned to each tent. Of the four stationed at each tent, two were randomly assigned to stay inside the tent (at opposite corners) and two to stay outside the tent (at opposite corners). During a specified 20-minute period during the night, each person kept count of the number of mosquito bites received. The goal of the study was to determine the effect of both Tent type (treated or untreated) and the Location (inside and outside) on the mean mosquito bite count.

The data for the study are shown in the table below. The summary values for the factors are given with A = Tent type and B = Location.

A1=30, A2=56, B1=27, B2=59, AB11= 11, AB12= 19, A21=16, AB22= 40

CM=924.5

These are the correct answers, but I don't understand how we got this.

Seasonal affective disorder (SAD) is a type of depression during seasons with less daylight (e.g., winter months). One therapy for SAD is phototherapy, which is increased exposure to light used to improve mood. A researcher tests this therapy by exposing a sample of patients with SAD to different intensities of light (low, medium, high) in a light box, either in the morning or at night (these are the times thought to be most effective for light therapy). All participants rated their mood following this therapy on a scale from 1 (poor mood) to 9 (improved mood). The hypothetical results are given in the following table.

(a) Complete the F-table and make a decision to retain or reject the null hypothesis for each hypothesis test. (Round your answers to two decimal places. Assume experimentwise alpha equal to 0.05.)

State the decision for the main effect of the time of day.

-Retain the null hypothesis

-Reject the null hypothesis.    

State the decision for the main effect of intensity.

-Retain the null hypothesis

-Reject the null hypothesis.    

State the decision for the interaction effect.

-Retain the null hypothesis.

-Reject the null hypothesis.    

(b) Compute Tukey's HSD to analyze the significant main effect.

The critical value is for each pairwise comparison.

We are in casino playing roulette, American version. We decided to play only red/black, i.e. to bet on red only.

We will use the Martingale strategy. A game starts with the first bet of 1 chip. If you win the game is over. You won a game. If you loose, you double your bet. You proceed to double your bet till you finally win or if you loose 6 in a row. Either way that concludes one game. You start a new game by betting 1 chip again.

Fill up the following table

From the table compute the probability of winning in a game. A game has two outcomes therefore it is a

______________________ experiment.

We made a PDF table for the game. Include the gain function.

Now we decide to play the game 12 times. Fill the table below.

For this table we used __________________ distribution

What is the probability of winning(making a profit) after 12 games?

What is the expectation of the gain after 12 games?

Should we Gamble?

Yes or No

Mike’s total utility from doing the same activity over and over is 50 utils after one repetition, 90 utils after two repetitions, 70 utils after three repetitions, 20 utils after four repetitions, -50 utils after five repetitions, and -200 utils after six repetitions. Write down his marginal utility for each repetition. Once Mike’s total utility begins to decrease, does each additional repetition of the activity hurt more than the previous one or less than the previous one?

Problem 2-18B Cost behavior and averaging

Chris Quill asks you to analyze the operating cost of his lawn services business. He has bought the needed equipment with a cash payment of $90,000. Upon your recommendation, he agrees to adopt straight-line depreciation. The equipment has an expected life of four years and no salvage value. Mr. Quill pays his workers $20 per lawn service. Material costs, including fertilizer, pesticide, and supplies, are expected to be $10 per lawn service.

Required

Determine the total cost of equipment depreciation and the average cost of equipment depreciation per lawn service, assuming that Mr. Quill provides 40, 50, or 60 lawn services during one month. Is the cost of equipment a fixed or a variable cost?

Determine the total expected cost of labor and the average expected cost of labor per lawn service, assuming that Mr. Quill provides 40, 50, or 60 lawn services during one month. Is the cost of labor a fixed or a variable cost?

Determine the total expected cost of materials and the average expected cost of materials per lawn service, assuming that Mr. Quill provides 40, 50, or 60 lawn services during one month. Is the cost of fertilizer, pesticide, and supplies a fixed or a variable cost?

Determine the total expected cost per lawn service, assuming that Mr. Quill provides 40, 50, or 60 lawn services during one month.

Determine the average expected cost per lawn service, assuming that Mr. Quill provides 40, 50, or 60 lawn services during one month. Why does the cost per unit decrease as the number of lawn services increases?

If Mr. Quill tells you that he prices his services at 30 percent above cost, would you assume that he means average or actual cost? Why?
