A Year 13 Statistics student was given an assignment where she had to design and conduct an experiment and analyse the data collected.

She decided to investigate whether being told that a quiz was easy or hard influenced the results of the quiz. All the students in a Year 9 class were given the same quiz after having been randomly allocated to one of three groups: Group 1 were told that it was a hard quiz, Group 2 were told it was an easy quiz and Group 3 were told nothing about the quiz. None of the students were told what the experiment was about.

She then carried out a randomisation test to compare the mean quiz marks for the three groups.

Which one of the following statements is false?

The response is the quiz mark.

There were 3 treatments; being told the quiz was easy, told it was hard or told nothing at all.

It was not possible to blind the students because they knew that they had been given a quiz.

The experiment used a completely randomised design.

The group that were told nothing about the quiz could act as the Control group.

For The introduction include

1) Background about bacteria. specifically the differences between gram + and gram - bacteria. Talk about B. subtilus and E. coli (what they are?)

2) Background on antibiotic resistance, How it formed and how is it affecting the society

3) State the objective of this experiment

4) predictions- please use what I wrote on the board. predictions need to be rationalized, not opinion oriented.

Please write this in order 1, 2, 3, 4. Make sure the organizations are good. also

- Include reference, literature reviews

-No question form

-Paragraph-wise

Methods

-Need to be PASSIVE, don't use I, you, we, the professor

-Make sure you use the correct and precise term

-Please don't divide them into sections, need to be in paragraph

-Need to mention the type of antibiotic used, bacterias used

-Treat this like a real lab experiment

-Don't mention we wait a week. After incubation, it's the measure of ZOI. and that's it.

-Don't be excessive. Only write enough so someone could replicate your experiment.

The mathematics department is considering revising how statistics is taught. In order to see if their changes will be effective in increasing student performance, they decided to run a Simulated Experiment. Previous semesters have that 10% of students receive an A in the class, 40% receive a B, and 20% receive a C. How would you assign values so you can use a Random Digit Table to run this experiment?

a) Assign 1 digit numbers as follows: 0 is A; 1, 2, 3, 4 are B; 5, 6 are C; 7, 8, 9 are D.

b) Assign 1 digit numbers as follows: 0 is A; 1, 2, 3, 4 are B; 5, 6 are C; 7, 8, 9 are other grades.

c) Assign 2 digit numbers as follows: 00-10 are A; 00-40 are B; 0-20 are C.

d) Assign 2-digit numbers as follows: 90-99 are A; 80-89 are B; 70-79 are C; 60-69 are D; and 00-59 are F.

e) This experiment cannot be simulated using a random digit table.

A bag contains 12 balls of the same shape and size.

Of these, 9 balls are blue, and the remaining 3 balls are red.

Suppose that you do the following iterative random experiment: In each iteration, 5 balls are removed randomly (without replacement) from the bag, in such a way that any 5 balls in the bag are equally likely to be the 5 balls that are removed. After doing this, you check whether among the 5 removed balls there are exactly 2 red balls. If so, then you STOP. Otherwise, you replace the 5 balls back into the bag, shake the bag up (to make sure it is randomly mixed again), and repeat the same experiment: random sample 5 balls from the bag, and check whether you have taken out exactly 2 red balls.

You repeat this until the process STOPs (i.e., when the 5 removed balls in some iteration contain exactly 2 red balls among them).

What is the expected number of times that you will sample 5 balls from this bag, in the above random experiment?

"Little Albert and Classical Conditioning"

The original article by Watson and Rayner was published in the Journal of Experimental Psychology in 1920. There is a reprint of the original article which can be found in the South University Online Library. Here is the reference for the article reprint: Watson, J. B., & Rayner, R. (2000).

There have been several classic experiments to study and describe classical conditioning; one of the more famous is the Little Albert experiment. Over the years, the experiment has lost some of its validity due to numerous interpretations by several introductory psychology textbooks. It is, therefore, beneficial to go back to the original (or primary) source and read what the authors of the experiment themselves had to say.

Read the article and answer the following questions:

In the study, what are unconditioned stimulus (US), conditioned stimulus (CS), and conditioned response (CR)?

Explain the concept of generalization in regards to Watson and Rayner's ability to condition Albert to react to different stimuli such as masks, other animals, and a fur coat?

Using examples from the study, explain the concept of extinction

Rankine cycle experiment:

5000ml water consumed in experiment used

Time (sec): 1055

Boiler, Temp (c): 167.199

Turbine In, Temp (c):109.3

Turbine ex, Temp (c): 97.79

Boiler Pres, (KPa) : 721.315

Turbine In Pres, (KPa): 85.639

Turbine Ex Pres, (KPa): 32.826

Fuel flow, (L/Min):5.842

Generator, (RPM): 1949.185

Voltage (volts): 7.443

Current (Amps): 0.135

Power (Watts): 1.002

Calculate:

1.Mass flow rate of water/ steam in the closed cycle.

2. Specific work generated by the turbine.

3. Power generated by the turbine.

4. Heat rejected to cooling system by the condenser.

5. Specific work into the pump.

6. Heat flux introduced by the boiler

Please Help me, Ive posted this question a few times,and I don't understand why they use turbine inlet pressure instead of the boiler pressure.

Whats also confusing me is how they get h1 ,h2,h3 and h4 from the tables if the figures do not correspond.

Id really appreciate it if someone can properly explain this to me.

Please use C++ for Mac (XCode)

In this program, a user can search for a name within a list of names. Here are the steps the program will implement:

1. Reads the names from the file names.txt into a vector that stores strings.

2. Sorts the names in alphabetical order using selection sort.

3. The program then prompts the user to enter a name.

4. The program then uses binary search to see if the name is in the list.

5. If the name is in the list, the program prints: "The name you entered is in the list!"

6. If the name entered was not in the list, the program prints "The name you entered was not in the list."

Notes: You will need to change your swap function to swap strings, like this:

void swap(string& x, string& y)

{

string temp = x;

x = y;

y = temp;

}

Create a class called Customer in three steps: • (Step-1): • Add a constructor of the class Customer that takes the name and purchase amount of the customer as inputs. • Write getter methods getName and getPrice to return the name and price of the customer. You can write a toString() method which returns printed string of Customer name and its purchase. • (Step-2): Create a class called Restaurant. • Write a method addsale that takes customer name and purchase amount of the customer in the class restaurant and stores it into an array list. • Write a method nameBestCustomer that returns customer name who bought highest sale in the restaurant. • (Step-3): Write a tester class that prompts the user to enter name and purchase of the customers and display the name of the customer who bought highest sales in the restaurant.
