The decision in any hypothesis is to reject the null hypothesis OR to fail to reject the null hypothesis.

1. Under what conditions do you reject the null hypothesis in any hypothesis test?
2. Find an example of a hypothesis test of the mean in your homework this week and use it to explain how a conclusion is written if the null hypothesis is rejected?
3. Find an example of a hypothesis test of the mean in your homework this week and use it to explain how a conclusion is written if the null hypothesis is not rejected?

Define the Elasticity of Demand for Labor. List the five benchmarks analysts use in its discussion and detail whether increased wages for each results in an increase in the total of wages received by workers in that labor market or not.

1. State the null and alternative hypotheses (take round 1 scores - round 4 scores).
2. Is this a lower tail, upper tail or two-tailed test?
3. Use Excel to carry out the test. Use a = 0.05. What is the value of the test statistic?
4. What is the p-value?
5. What is your conclusion using a = 0.05?
6. State your conclusion in words a non-statistician could understand.

A student survey was completed by 446 students in introductory statistics courses at a large university in the fall of 2003. Students were asked to pick their favorite color from black, blue, green, orange, pink, purple, red, yellow.

(a) If colors were equally popular, what proportion of students would choose each color? (Round your answer to three decimal places.)

(b) We might well suspect that the color yellow will be less popular than others. Using software to access the survey data, report the sample proportion who preferred the color yellow. (Round your answer to two decimal places.)

(c) Is the proportion preferring yellow in fact lower than the proportion you calculated in (a)?

(d) Use software to produce a 95% confidence interval for the proportion of all students who would choose yellow.
(e) How does your confidence interval relate to the proportion you calculated in (a)?

it is strictly below that proportion it contains that proportion     it is strictly above that proportion

This unit you have learned about the many issues effecting the quality of healthcare in the U.S. There are many policies and incentives the government has developed that attempt to address quality and the care that healthcare institutions provide to their patients. For this assignment, I would like for you to answer the questions below. I want to hear your opinion about the quality of care in the U.S. and use research to back up your opinions. What are some of the issues going forward with the quality of healthcare? How will reimbursement be influenced? What policies are on the table that could influence these issues? And how do you think the healthcare industry will be influenced? Write a minimum 1-page essay on the above questions. Be sure to clearly define equity in your own terms and use this to support your statements. The paper must be written using APA style. A minimum of 2 sources other than your textbook must be cited.

Recall again that Rind & Bordia (1996) investigated whether or not drawing a happy face
on customers’ checks increased the amount of tips received by a waitress at an upscale
restaurant on a university campus. During the lunch hour a waitress drew a happy,
smiling face on the checks of a random half of her customers. The remaining half of the
customers received a check with no drawing (18 points).
The tip percentages for the control group (no happy face) are as follows:
45% 39% 36% 34% 34% 33% 31% 31% 30% 30% 28%
28% 28% 27% 27% 25% 23% 22% 21% 21% 20% 18%
8%
The tip percentages for the experimental group (happy face) are as follows:
72% 65% 47% 44% 41% 40% 34% 33% 33% 30% 29%
28% 27% 27% 25% 24% 24% 23% 22% 21% 21% 17%

This time, you are to perform a “hypothesis test” using the tip data, answering each of
the questions below. For short-answer questions, be brief. However, you must give
enough detail to justify your answers. Single-sentence responses will generally not
suffice, but do not exceed a paragraph for any given answer.

o. Considering both the probability value and effect size measure, what
interpretations would you make about the findings? That is, what are your
conclusions about the effects of leaving happy faces on checks?

The age distribution of the Canadian population and the age distribution of a random sample of 455 residents in the Indian community of a village are shown below.

Use a 5% level of significance to test the claim that the age distribution of the general Canadian population fits the age distribution of the residents of Red Lake Village.

(a) Find the value of the chi-square statistic for the sample. (Round your answer to three decimal places.)

Write, test, and debug (if necessary) JavaScript scripts for the following problem. You must write the HTML file that references the JavaScript file.

Use prompt to collect names of persons from the user. When the user enters ‘DONE’, your script should stop collecting more names. Then, it should ask the user to specify the following style properties:

Border size? 2px, 5px, or 8px.

Border Color? blue, red, green, and black.

Border style? solid, dotted, dashed, and double.

The HTML document should display the person names in a table using the style properties specified by the user.
