Unspoken Rules

• Why do we say, “Bless You!” when someone sneezes? Do all people say it?

• Why do we instinctively walk on the right side of a sidewalk? Do all people walk on the right side?

• Why do people instinctively line up when they are trying to get in somewhere or talk to someone? What would happen if they didn’t form a line? Who decided we should stand in a line?

• Why do we shake hands when we meet someone? Do all people shake hands? Who started this?

We do things every day without even thinking about them. They are the unspoken rules of our society. In this lab, you will choose a common social rule. You can use one of the examples above or choose one of your own. Use online sources, as well as what you learned in the unit, to help you answer the questions.

1 . What is the unspoken rule that you decided to research?

2. Where did this unspoken rule come from?

3. Is this rule universal or particular to your country or region?

4. What would happen if everyone suddenly stopped following this unspoken rule?

5. Cite the sources you used for your research.

1. what is counter current machenism? 
2. Drug of choice for placental separation in abortion? 
3. Amount of haemoglobin in each RBC? 
4. Type 1st hypersensitivity induced by which Ig_?
5. 3D sign of pellagra? 

Consider the following three (3) research questions. For each of them:
(a) identify what type of information the research question focuses on and explain why;
(b) identify what data collection technique provides that type of information and explain why. (1-2 line answers)

Standard Error of the Mean, Confidence Intervals, & The Z Test

Report the values you are using for this assignment.

HR Mean (µHR)

(one decimal)

HR Std Dev (sHR)

(two decimals)

RR Mean (µRR)

(one decimal)

RR Std Dev (sRR)

(two decimals)

90.7

6.83

12.6

1.96

Make sure these initial values have been marked correct.

Follow the rounding instructions carefully.

Task 1:  Standard Error of the Mean (SEM) for Different Sample Sizes

Imagine that your HR and RR data sets were very large (N=500). Calculate SEM based on the population standard deviations calculated in assignment 2, and the sample sizes given in the table. Carefully round the SEM value to 2 decimals for each calculation.

Formula: Standard Error of the Mean (SEM or sM or  ) = 

SEM

Heart Rate

Respiratory Rate

SEM if n = 9

2.28

0.65

SEM if n = 25

1.37

0.39

SEM if n= 100

0.68

0.2

What happens to the value of the SEM as the sample size increases?

By observing the values, we can conclude that as the sample size (n) increases the standard error of the mean decreases.

Question:

Task 5: Z Test: Calculate the Z statistic (Zobt) and compare to Zcrit

*Reminder! Your data is now viewed as a sample. Use the σ given in Task 4 to calculate SEM.

1) Use 3.16 as the square root of 10 to calculate the Standard Error of the Mean.  

(You may also see SEM expressed as  sM or  )

            (SEM or sM or  ) =       Round to 2 decimals.

2) Calculate the difference between the means (sample minus population)

!! If the difference is zero, use 1.1 as the difference.

3) Calculate ZOBT using:    

HR

SEM

ZOBT

Value

90.7 – 81.36

zHR = 2.08

RR

SEM

ZOBT

Value

12.6 – 15.69

zRR = -2.54

Alpha level (α) for all test is 0.05. The Zcrit values are:

Two Tailed

-1.96 and +1.96 (or ±1.96)

One Tailed

If difference between means is negative: -1.65

If difference between means is positive: +1.65

4) Compare ZOBT to ZCRIT. Is ZOBT located in the Zone of Rejection? (aka the Critical Region)

Sketching a number line with critical values and zones identified helps with this.

        Zone of                                                                                                           Zone of

       Rejection       -----------------------------Do Not Reject---------------------------------       Rejection

                      -1.96                                           0                                                 1.96                                                                                                                                                                                                                                                                        

Use the same principle for the one tailed comparison. In that case there will only be one Zone of Rejection, based on whether Zcrit was positive or negative.

Task 6: Z Test: Decisions, Effect Size, and Potential Error Type

1) Answer the first two questions (Yes or No) based on what you found in Task 2.

2) Calculate effect size using Cohen’s d:   d =      (Reported as a positive value.)

(Effect size is not usually reported if the null is not rejected, but do it here just to build skills.)

3) There is always a theoretical statistical error potentially present after a hypothesis is tested. Name the potential error that must be acknowledged because of your decision.

HR

Two Tail

One Tail

Is your decision to Reject the Null?

Can you say the sample mean is statistically different from the population mean?

What is the effect size? (Cohen’s d)

1.59

What type of statistical error might be present?

RR

Two Tail

One Tail

Is your decision to Reject the Null?

Can you say the sample mean is statistically different from the population mean?

What is the effect size? (Cohen’s d)

What type of statistical error might be present?

→ Consult the notes for detailed information on one and two tailed tests, hypothesis construction, alpha level, critical values, Zone of Rejection, types of error, and effect size by Cohen’s d.

→ The GWFW book uses the term Z ‘score’ even when comparing means; perhaps to highlight the similarity between the formula for a Z score (with sigma ‘σ’ in the denominator) and the formula for the Z statistic (with SEM in the denominator.) At the Z test level, a statistical test for comparing means is being performed by calculating a Z statistic. When the context is clear, ‘Z value’, or just ‘Z’, could be used as a general term of reference, but you should be aware that a Z score is not the same as a Z statistic.

Directions: Write an advertisement according to the instructions below.

1. Writing advertising copy can be fun, especially if you have a flair for humor. In this project, your first task is to think up an imaginary product you would like to advertise.
2. Then write enough copy for a 30-second television commercial. First develop a clever name for your product. Many students like to name products after their friends or teachers. Any product you can imagine is fair game - from sweat socks to gold-plated fly swatters.
3. You may imitate commercial messages you have heard in the mass media, making it humorous or serious as you desire.
4. Be certain to use correct capitalization and punctuation in your writing.

When javascript came into existence it was mainly for the web front end example in 1993 when websites were getting famous everyone wanted to have their own website. Netscape came up with this programming language called javascript with the help of sun microsystem and they released javascript in their netscape navigator too. The only only use case you can find is building the front end of the web application. This course is not designed in a normal fashion or the traditional fashion. The idea is to learn javascript from start to end. can run javascript on your os now or on your machine right so just to give you a hint that is possible with the help of nodejs so node. js is a runtime environment imagine a place where you can run Javascript. Every time you watch a video do it on your machine. Practice it 's a programming language right you you will remember everything you have to practice practice makes you perfect okay so i would also suggest that you change the code do some experiments and that's how you go so that 's it from this video i hope you're excited hit that like button.

City Government Review Page

Comparing and Contrasting: Copy and paste the chart below in a Word document. Explain the advantages and disadvantages of each type of city government. Once you have completed your chart, submit it to your instructor.

Subject-civics

Read the information in the "Summary of Home Rule". Discuss what are the advantages and disadvantages of a city (in this example--a county--) assuming the responsibilities of governing its residents under the "Home Rule" ordinances. You do not have to read the charter itself, nor the "Second Class County Charter Laws." However, many advantages will be found in the reading while few disadvantages are disclosed. Those you'll have to think about, and decide upon the disadvantages for yourself (hint: think of everything that a city must do in order to become chartered with "Home Rule").
