A political scientist hypothesize that a political ad will increase attitudes about a particular issue. The scientist randomly asks 25 individuals walking by to see the ad and then take a quiz on the issue. The general public that knows little to nothing about the issue, on average, scores 50 on the quiz. The individuals that saw the ad scored an average of 47.55 with a variance of 28.73. What can the political scientist conclude with an α of 0.05?

a) What is the appropriate test statistic?
---Select--- na z-test one-sample t-test independent-samples t-test related-samples t-test

b)
Population:
---Select--- the ad individuals walking by general public the particular issue the political ad
Sample:
---Select--- the ad individuals walking by general public the particular issue the political ad

c) Compute the appropriate test statistic(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
critical value =  ; test statistic =
Decision:  ---Select--- Reject H0 Fail to reject H0

d) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below.

e) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d =  ;   ---Select--- na trivial effect small effect medium effect large effect
r² =  ;   ---Select--- na trivial effect small effect medium effect large effect

f) Make an interpretation based on the results.

Individuals that watched the political ad scored significantly higher on the quiz than the general public.Individuals that watched the political ad scored significantly lower on the quiz than the general public.    Individuals that watched the political ad did not score significantly different on the quiz than the general public.

A 0.4485 g sample of pewter, containing tin, lead, copper, and zinc, was dissolved in acid. Tin was precipitated as SnO2·4H2O and removed by filtration. The resulting filtrate and washings were diluted to a total volume of 250.0 mL. A 15.00 mL aliquot of this solution was buffered, and titration of the lead, copper, and zinc in solution required 34.07 mL of 0.001534 M EDTA. Thiosulfate was used to mask the copper in a second 20.00 mL aliquot. Titration of the lead and zinc in this aliquot required 34.56 mL of the EDTA solution. Finally, cyanide was used to mask the copper and the zinc in a third 25.00 mL aliquot. Titration of the lead in this aliquot required 25.76 mL of the EDTA solution. Determine the percent composition by mass of each metal in the pewter sample.

Conflict in an Emergency Situation: A Case Study

You are the director of Public Health Preparedness in Puerto Rico. In 2017, Puerto Rico was hit by Hurricane Maria. Puerto Rico has major infrastructure deficiencies, and the Puerto Rico Electric Power Authority has been unable to re-install power to remote areas. Six months after the hurricane hit the island, 100,000 Puerto Ricans are still without power (vox.com downloaded on 5/14/18). On Saturday morning, a social worker calls to inform you that a 31-year-old resident, Raul Ortega Gonzalez, has remained in his family house without power and is in need of surgery for a painful hernia. A visiting nurse stopped by his home this morning and recommended that he be taken to a hospital in San Juan to receive the treatment he needs. He is refusing to leave his home as he believes that his home will be vandalized if left empty. The nurse called on the state social worker to speak with the Ortega Gonzalez family and the ambulance service to transport Raul to San Juan. This family has weathered many storms, and they have moved to New Jersey from Puerto Rico to allow their younger children to remain in school while Puerto Rico regains power. The family plans to return to the family home at the end of the school year. The family does not understand why the surgery cannot wait the one month left of the school year and are infuriated that the state would impose its values on their family. Furthermore, how can the state not understand Raul’s concerns with the vandalism that has affected the area?

As the director of Public Health Preparedness, you receive a call from the ambulance service staff later in the morning, and they inform you that they are not wasting their time with Raul Ortega Gonzalez—that the family can do with him what they choose. The head nurse is terribly upset as she believes that his life is being placed at risk and insists that the ambulance service must take Raul to the hospital.

1. Identify the sources for this conflict.
2. Why has the conflict escalated?
3. What would you do to assist in the negotiations with Mr. Ortega Gonzalez?

Two astronauts, Hans and Dexter, are on a spacewalk floating at rest next to their space vehicle. They argue and Hans shoots Dexter with a handgun. The bullet has a mass of 0.015 kg and a muzzle velocity of 250 m/s. Hans now finds himself drifting away from the spacecraft

a.) Hans and his spacesuit have a mass of 200 kg. how fast is he drifting away

b.) Hans only had one bullet, but he is holding a gun that has a mass of 1.1 kg. how fast must he throw it to stop drifting away from the spacecraft?

c.) Meanwhile, on earth, a solid cylinder of mass 5kg rolls without slipping toward a hill with a velocity of 5 m/s. how high up the hill will the cylinder roll?

Iguana, Inc., manufactures bamboo picture frames that sell for Tk. 25 each. Each frame requires 4 feet of bamboo, which costs Tk. 2.00 per foot. Each frame takes approximately 30 minutes to build, and the labor rate averages Tk. 12.00 per hour. Iguana has the following inventory policies: 1) Ending finished goods inventory should be 40 percent of next month’s sales. 2) Ending direct materials inventory should be 30 percent of next month’s production. Expected unit sales (frames) for the upcoming months follow: March: 275, April:250, May: 300, June: 400, July: 375, August: 425 Variable manufacturing overhead is incurred at a rate of Tk. 0.30 per unit produced. Annual fixed manufacturing overhead is estimated to be Tk. 7,200 (Tk. 600 per month) for expected production of 4,000 units for the year. Selling and administrative expenses are estimated at Tk. 650 per month plus Tk. 0.60 per unit sold. Iguana, Inc., had Tk. 10,800 cash on hand on April 1. Of its sales, 80 percent is in cash. Of the credit sales, 50 percent is collected during the month of the sale, and 50 percent is collected during the month following the sale. Of direct materials purchases, 80 percent is paid for during the month purchased and 20 percent is paid in the following month. Direct materials purchase for March 1 totaled Tk. 2,000. All other operating costs are paid during the month incurred. Monthly fixed manufacturing overhead includes Tk. 150 in depreciation. During April, Iguana plans to pay Tk. 3,000 for a piece of equipment. Prepare the following for Iguana, Inc., for the second quarter (April, May, and June). Include each month as well as the quarter 2 total for each budget. 1. Sales budget. 2. Production budget. 3. Direct materials purchase budget. 4. Direct labor budget. 5. Manufacturing overhead budget. 6. Budgeted cost of goods sold. 7. Selling and administrative expenses budget

Write a Python function that receives a stack object s, where the items in the stack are only numbers in the set {0,1} and returns the number of 1's in the stack s. The function must satisfy the following restrictions:

• the state of the stack must be preserved; ie., after calling this function the state of the stack s must be the same it was before the function was called.
• The function cannot use any additional variables of any of the collection types such as lists, stacks, dictionaries, strings etc.
• The function cannot use any global variables.
• Since the implementation of Stack is not known you must use the API given in the Table 1.

For example, if the stack contains 0,0,1,1,0,1,0, the function must return 3 and the stack must still contain 0,0,1,1,0,1,0.
