Write a program that meets the following requirements:

Cat Class

1. Create a class called Cat which has only the following instance variables:

- name

- breed

- number of legs

- year born

2. Create the no-argument constructor
3. Create the constructor which uses all fields as parameters
4. Write the getter and setter methods for all instance variables
5. Override the toString method using the example shown above

There should be NO main method in the Cat class.

CatTester Class

1. Create a class called CatTester which constructs 10 different Cat objects
2. Add each Cat object to an array
3. Use an enhanced for loop to SOP each Cat reference
4. Use a second for loop to SOP only those Cats that are born after 2004 and have legs greater than 3

• You should use the class names of Cat and CatTester

Statistics exercises

Friedman’s K/One-way repeated measures ANOVA

1. Suppose you are interested in learning if practice on the ACT improves test scores. You sample a random group of 10 people and ask them to take the ACT 1 time per week for 3 consecutive weeks. Use the data below to determine if practice improves test scores.

1. State the hypotheses

2. Select an alpha level and one- or two-tailed

3. Select and compute the appropriate statistic

4. Report in APA style the df and p-value.

5. Accept or reject the null and draw an inference if one is warranted.

Descriptive Statistics:

In certain states, savings banks are permitted to sell life insurance. The approval process consists of underwriting, which includes a review of the application, a medical information bureau check, possible requests for additional medical information and medical exams, and a policy compilation stage, in which the policy pages are generated and sent to the bank for delivery. The ability to deliver approved policies to customers in a timely manner is critical to the profitability of this service to the bank. Let’s define the variable of interest as the total processing time in days. You collect the data by selecting a random sample of 27 approved policies during a period of one month:

73, 19, 16, 64, 28, 28, 31, 90, 60, 56, 31, 56, 22, 18, 45, 48, 17, 17, 17, 91, 92, 63, 50, 51, 69, 16, 17

1. Compute the mean, median and mode

2. Compute the range, interquartile range, variance, standard deviation ** for IQR would it be 61.5-18.5=43 OR 63-18=45??

3. Construct a frequency table and a histogram. Are the data skewed? If so, how?

4. What would you tell a customer who enters the bank to purchase this type of insurance policy and asks how long the approval process takes?

You measure 42 textbooks' weights, and find they have a mean weight of 74 ounces. Assume the population standard deviation is 11.4 ounces. Based on this, construct a 90% confidence interval for the true population mean textbook weight. Give your answers as decimals, to two places

_____< μ<______

D.G. is a 74-year-old woman who arrives at the emergency room complaining of shortness of breath, palpitations (for 2 days), and lower extremity edema. Her medical history includes diabetes mellitus, hypertension, heart failure with reduced ejection fraction, and osteoarthritis. She had a left heart catheterization and coronary angiography last year and has no significant coronary artery disease. She has a biventricular pacemaker/implantable defibrillator for heart failure symptom treatment and sudden cardiac death prevention. The patient’s current medications are losartan 100 mg/d, metoprolol succinate 50 mg/d, metformin 500 mg twice daily, spironolactone 25 mg/d, furosemide 40 mg/d, and naproxen 500 mg twice daily. Vital signs are as follows: blood pressure of 140/80 mm Hg, respiratory rate of 30 bpm, and heart rate of 120 bpm. ECG shows atrial fibrillation with a rapid ventricular response. Echocardiography reveals a moderately dilated left atrium, left ventricular systolic ejection fraction of 35% (unchanged), chronic kidney disease (baseline serum creatinine 1.01 mg/dL), and moderate mitral regurgitation. Pertinent laboratory values include the following: hemoglobin 12 g/dL, hematocrit 36%, platelets 300,000/microliter, and serum creatinine 1.20 mg/dL (estimated creatinine clearance 39 mL/min). Her weight is 60 kg (increased from 55 kg), and height is 5 ft 3 inches. She does not smoke and does not drink alcohol. Dietary habits include one can of Ensure daily, with other meals provided by a social service agency (Meals on Wheels). Social concerns include the fact she lives alone, but a son visits every 1 to 2 weeks and transports her to physician appointments. She is living on a limited budget. With regard to her medication adherence, her son states that she occasionally forgets to take her afternoon medications, but overall, she is considered to be reasonably adherent with her drug regimens.

Diagnosis: Atrial fibrillation, acute onset

Answer the following questions. Include two references, cited in APA style.

List specific goals of treatment for D.G.

What drug therapy would you prescribe for stroke prevention in atrial fibrillation? Why?

What are the parameters for monitoring success of the anticoagulant therapy?

Discuss specific patient education based on the prescribed therapy.

List one or two adverse reactions for the selected agent that would cause you to change therapy.

What would be the choice for the second-line therapy?

What OTC or alternative medications would be appropriate for D.G.?

What lifestyle changes would you recommend to D.G.?

Describe one or two drug–drug or drug–food interactions for the selected agent.

Moist air initially at T₁ = 140°C, p₁ = 4 bar, and relitive humidity = 74% is contained in a 2.0-m³ closed, rigid tank. The tank contents are cooled to T₂ = 35°C.

Determine the temperature at which condensation begins, in °C

Historically emergency responders respond in less than 5 minutes 74% of the time. A recent sample of n = 715 found 70% of emergency calls had a response time of less than 5 minutes. Perform a hypothesis test with α = 2.5% to see if the response time percentage has significantly decreased.

A. What is H_o?

B. What is H₁?

C. What is the value of the test statistic?

D. What is the value of the critical value?

E. What is the conclusion to this hypothesis test?

Females have a mean pulse rate of 74 beats per minute (bpm) and a standard deviation of 12.5

    bpm. If fifty females are randomly selected, what is the probability that their mean pulse rate

    is greater than 79 bpm?
