Regarding problem R2 from chapter 26. Make a box representing a roulette wheel with 18 tickets that represent red and 20 that represent black or green. Draw 3800 times with replacement from this box and record the number of tickets drawn that are red. Repeat this process 10,000 times. What is the fraction of times (out of these 10,000 repeated trials) were the number of red tickets drawn at least 1,890? How does this compare to the P-value you got in the problem? Can you use pbinom( ) to compute this probability? Are these numbers different? Why?

"With a perfectly balanced roulette wheel, in the long run, red numbers should turn up 18 times in 38. To test its wheel, one casino records the results of 3800 plays finding 1890 reds numbers.Is that too many reds. Or chance variation?"

How do I compute this on R?

A team of researchers has developed a new weight loss supplement. They want to know if patients who use the new supplement for four weeks lose any weight. The supplement has some minor side effects including mild headaches and achiness. If the researchers obtain evidence of weight loss they will proceed to produce the supplement commercially and sell it for a large profit. If they do not obtain evidence of weight loss, the project will be ended.

1. State the null and alternative hypotheses that the researchers should test. Use u_d to denote the mean weight loss computed as beginning weight minus final weight
2. Type I Error:
   1. What does a Type I error mean in this situation? Be sure your answer specifically states the error in terms of this scenario.
3. 2. What are the consequences of making a Type I error in this scenario?
4. Type II Error:
   1. What does a Type II error mean in this situation? Be sure your answer specifically states the error in terms of this scenario.
5. 2. What are the consequences of making a Type II error in this scenario?
6. In this scenario, is a Type I or Type II error more serious? Or, are they equally serious? Explain your reasoning.
7. If you were working with this research team, what alpha level would you use? Explain your reasoning.

Given what we know about brain mechanisms in memory, are our memories accurate? Explain your answer using information on how memories are stored in the brain.

You are to develop from the beginning a web site about yourself with regards to your course studies and any certifications you have done so far. This web site provides certain required details about your education/studies which you did. You will design and develop your web site with Notepad/Notepad++, HTML, Java Script and CSS. The purpose of this assignment is for you to build a web site that will contain some details about all of your course degrees you have achieved so far including all the certifications with, e.g., the number of degrees you are holding so far, the number of institutes you enrolled yourself, etc. This assignment involves creation of three HTML files corresponding to the three pages of your web site and all are connected to an external CSS file. You will need to determine how your site will be designed and then you will develop the pages using HTML, Java Script and CSS. The pages and CSS file you will develop are explained below. Home page (.HTML file) The first page of your site the user sees will be a home page. This page will be a welcome to the site. You will explain to the user what the site is about. The content of the page will include at least two paragraphs. An appropriate heading must be placed at the top of the page indicating what the page or site is about. The word limit for this page, excluding the heading, is 130 – 150 words. You must keep the number of words within this range. In the home page, add two links for “Course details” page and “About Me” page. NOTE: All pages must have links to the other pages.

Past Course details page (.HTML file) Begin this page with an appropriate heading (as all pages of the site will have) reflecting that this page deals with details about all the unit courses. Do not use “Course details” in the heading but use another title for your heading.

Current Course details page (.HTML file) This page conveys certain aspects about all the unit course details. Like the previous page, show a heading at the top of the page. Do not use “Current course details” in the heading text but use some other title.

Cascading Style Sheet Use CSS file for formatting used for all web pages.

Task 1: Develop a web site about yourself with regards to your course studies and any certifications you have done so far. This web site provides certain required details about your education/studies which you did. You will design and develop your web site with Notepad/Notepad++, HTML, J

Task 2: After developing the website, explain the characteristics of that website and associated authoring/management issues.

Need to add 4 courses for past and for courses for current study. the writing segments will be added by myshelf. just need the required codes.

Problem 4)   About 7% of men in a population are red-green colour blind due to a sex-linked recessive gene. Assuming random mating in the population with respect to colour blindness;

b) What percentage of women would be expected to be heterozygous?

c) What percentage of men would be colour blind in the next generation?

Provide an example of a capital budgeting project for an organization with which you are familiar. Explain in detail how you would conduct a scenario analysis and a sensitivity analysis for this project. Explain what information each type of analysis provides that the other does not.

Big Red soda is the "Faygo" of Texas. A local Texas grocery chain called H-E-B carries both name-brand Big Red soda and their store-brand equivalent called Wild Red soda. It is known that the sugar content of Big Red 20 ounce bottles is normally distributed with a mean of 63 g and a standard deviation of 1.1 g. It is also known that the sugar content of Wild Red 20 ounce bottles is normally distrbuted with a mean of 68 g and a standard deviation of 2.3 g.

An H-E-B worker find a pallet of 20 ounce red sodas, but the labels are missing so he is not sure if it is Big Red or Wild Red. In order to not waste the pallet of soda, he grabs a 20 ounce red soda at random and decides to test the amount of sugar in the drink. He sets up the following hypotheses:

H₀: The 20 ounce soda is Big Red versus H_a: The 20 ounce soda is Wild Red

He will use the following rule:
If the sugar content of the 20 ounce red soda is 65 g or more, he will decide that the soda is Wild Red (H_a).
But if the sugar content of the 20 ounce red soda is less than 65 g, he will decide that the soda is Big Red (H₀).

For this situation, find the value of β.--------Please show work!!
