A local police chief claims that 76%76% of all drug-related arrests are never prosecuted. A sample of 700700 arrests shows that 72%72% of the arrests were not prosecuted. Using this information, one officer wants to test the claim that the number of arrests that are never prosecuted is different from what the chief stated. Is there enough evidence at the 0.010.01 level to support the officer's claim?

Suppose Liam's Kitchen, a restaurant,: serves two items: hamburgers and french fries. With all employees working diligently, the restaurant can produce these combinations each hour.

Type of Product:   Production Alternatives

A B C D E

Burgers 0 10 20 30 60

Fry Bags 100 90 70 40 0

Calculate the opportunity costs of moving from one point to each of the others: Provide the answers after showing all work, and explain if theses costs are constant. What would it mean if the kitchen was actually making 35 Burgers and 45 Fries from Fry Bags? What would it mean if the kitchen was actually making 15 Burgers and 70 Fries from fry bags?

(Rubric: 12.5 points - 1) calculate the opportunity costs and show the work.; 2) Explain the 35-45 question; 3) Answer whether the opportunity costs are fixed or not; and 4) Explain the 15-75 question. 10 points - one of the two explanations is only a "word" not a sentence, and/or one of the points isn't identified. May not be some calculations. 8 points - Neither explanation is a complete sentence, and some of the points aren't identified. May not be many calculations. 6.25 points or less points - This is a failing score for the question. The answer is worse than that required for 8 points.)

The following income statement items appeared on the adjusted trial balance of Foxworthy Corporation for the year ended December 31, 2018 ($ in 000s): sales revenue, $21,600; cost of goods sold, $14,150; selling expenses, $2,230; general and administrative expenses, $1,130; dividend revenue from investments, $130; interest expense, $230. Income taxes have not yet been accrued. The company’s income tax rate is 40% on all items of income or loss. These revenue and expense items appear in the company’s income statement every year. The company’s controller, however, has asked for your help in determining the appropriate treatment of the following nonrecurring transactions that also occurred during 2018 ($ in 000s). All transactions are material in amount.

  1. Investments were sold during the year at a loss of $230. Foxworthy also had unrealized holding losses of $130 for the year on investments.
  2. One of the company’s factories was closed during the year. Restructuring costs incurred were $1,300.
  3. During the year, Foxworthy completed the sale of one of its operating divisions that qualifies as a component of the entity according to GAAP regarding discontinued operations. The division had incurred operating income of $730 in 2018 prior to the sale, and its assets were sold at a loss of $1,940.
  4. A positive foreign currency translation adjustment for the year totaled $670.


Required:

Prepare Foxworthy’s single, continuous statement of comprehensive income for 2018, including earnings per share disclosures. Use a multiple-step income statement format. Two million shares of common stock were outstanding throughout the year. (Enter your answers in thousands of dollars, except earnings per share. Amounts to be deducted should be indicated with a minus sign. Round EPS answers to 2 decimal places.)

Using the below question and values how do you calculate the standard deviation without using a calculator (by hand) of (s1^2/n1+s2^2/n2) with the standard deviation answer being 1.4938 and 1.1361
/sqrt(1.4938^2/10 + 1.1361^2/10)
Choose two competing store and compare the prices of 10 items at both stores. Preform a two-sample hypothesis test to try an prove if one store is more expensive than the other based on your sample. Store A item #1-$5.49, #2 $3.77, #3 $0.87, #4 $3.29, #5 $4.79, #6 $1.99, #7 $1.33, #8 $2.19, #9 $2.79, #10 $3.99 Store B items #1 $4.59, #2 3.99, #3 $1.79,  #4 $2.99, #5 $4.59, # $1.79, #7 $1.99, #8 $2.19, #9 $2.79, #10 $3.99

Hypothesis:
H0 ; mu1= mu2
HA: mu 1 > mu2

test statistics:

t = (x1-x2)/sqrt(s1^2/n1+s2^2/n2)
= (3.05 - 3.07)/sqrt(1.4938^2/10 + 1.1361^2/10)
= -0.0337

p value = .4872

FAil to reject the H0

A psychologist wants to determine whether speaking more than one language fluently has cognitive benefits. They conduct a study in which a total of 72 participants are tested on a task measuring cognitive control. Half the participants are male, and half are female and speak one, two, or three+ languages fluently. For a two-way ANOVA with SSbetween = 148; SSLanguage = 80; SSSex = 50; SStotal = 350, what can the psychologist conclude? Be sure to address all hypotheses. Assume the DV is continuous.

It has been suggested that the highest priority of retirees is travel. Thus, a study was conducted to investigate the differences in the length of stay of a trip for pre- and post-retirees. A sample of 696 travelers were asked how long they stayed on a typical trip. The observed results of the study are found below.  

# of nights pre-retirement post-retirement total
4-7 239 169 408
8-13 78 68 146
14-21 34 58 92
22 or more 13 37 50
Total 364 332 696

With this information, construct a table of estimated expected values.

# of nights pre-retirement post-retirement
4-7
8-13
14-21
22 or more

Now, with that information, determine whether the length of stay is independent of retirement using alpha = 0.01

a) chi squared =

b) Find the degrees of freedom:

c) Find the critical value:

d) The final conclusion is

A. There is not sufficient evidence to reject the null hypothesis that the length of stay is independent of retirement.

B. We can reject the null hypothesis that the length of stay is independent of retirement and accept the alternative hypothesis that the two are dependent.

When events occur in a time period (0, a) with regard to a Poisson process, it is well known that, conditioned on the total number of events k, the joint distribution of the times at with the events occur follows a uniform distribution in (0, a) k. That is, if Xi represents the arrival time of one of them, then Xi ∼ U(0, a) and it is independent of the other X’s.

1. If ten patients visit the Emergency Room (ER) of a hospital between 9 and 10, what is the probability that fifth of them reaches the ER before 9:30?

2. If ten patients visit the ER between 9 and 10, what is the probability that the first 3 of them arrive before 9:20, 4 of them between 9:20 and 9:40, and the last 3 of them after 9:40?

3. If two patients visit the ER of a hospital between 9 and 10, what is the conditional distribution of the time at which the second patient arrived at the ER given that the first patient arrived at time t1?

Think about the sources of conflict that were identified through our class content on conflict. Choose two of those sources, and match each with what you believe is an appropriate conflict management style to utilize when resolving a conflict within that source. Defend and justify your discussion using examples.
