Step 1: Calculate the mean, median, and standard deviation for ounces in the bottles. Answer: Mean 14.87 Median 14.8 Standard Deveiation 0.55033 For the full calculation, refer to Appendix #1 at the end of the essay. Step 2: Create a 95% Confidence Interval for the ounces in the bottles. Answer: x ̅=14.87 ,s=0.5503 , n=30 , α=0.05 The level of confidence is at 95%. Use the following formula to determine the confidence interval: (x ̅-t_(α/2) (s/√n),x ̅+t_(α/2) (s/√n)) t_(α/2)=t_0.025=2.045 Substitute the values into the formula: (14.87-2.045(0.5503/√30),14.872.045(0.5503/√30)) = (14.665,15.075) The calculation above clearly states that the confidence interval at 95% confidence is approximately 14.665 - 15.075 ounces. Step 3: Crete a hypothesis to test the claim that a bottle contains less than sixteen ounce is correct. Be sure to clearly state the logic of the …show more content…
Therefore, the null hypothesis H0: µ ≥ 16 ounces is rejected, leading to the mean being less than sixteen ounces. Step 4: The following is discussion based on the conclusion of the test: If it is concluded that there are less than sixteen ounces in a bottle of soda, create a hypothesis on three possible causes. Followed by the suggestions of the strategies to avoid the deficit in the future. Answer: When analyzing the test, one can conclude that the complaint about the bottles not containing sixteen ounces tends to be correct. Possible reasons for the bottles not containing the amount as marketed are listed below. A malfunction is the software used by the company. Errors such as: leaks in containers, spills when filling the bottles and malfunction in the soda dispensers used by the company. Failure by the company employees that check the bottles to ensure the proper amount of

Panic hit my parents. It 's senior year, I just got accepted into UW Tacoma and they see the tuition fees. They were already in shock when they had seen my Application Fee was 70 dollars. Since we are residents of Washington my tuition fee is even higher; being about 5 thousand dollars more; the estimated tuition fees for nonresidents costs $34,791, not even counting the cost of living and supplies. The estimated costs to live on campus is $11,962 per year, which still doesn 't count the costs of food; which the estimated cost of food per year is $512 but, that is just for a meal card for their cafeteria not even counting outside expenses.

Anderson, Indiana used to be an exciting town full of businesses and factories. It was a great place to live and many people wanted to live here because there were many opportunities and places for people to get jobs. In the last thirty or so years, Anderson has become the exact opposite of what it used to be. There is not much of anything here now and everyone who currently resides here is looking for a way out. There are a few to no successful factories like there used to be in Anderson years ago.
Within the data for the women who belong to the Medina Early Childhood Parent Teacher Association (MECPTA), women of child-bearing age, and the residents of Medina County, there is an overall obesity rate among the women. More than 80% of adults do not meet the guidelines for aerobic and muscle-strengthening activities. Only 10% of the activities within the MECPTA are active and physical. Physical activity decreases by an average of 1.4 hours per week after women have children. Within Medina County, there are 17 parks, but they are rarely used by the MECPTA.
After reviewing the resources in the Weekly Guide/Week 2, identify a clinical problem within the nurse’s practice setting related to patient care. The nurse currently does not provide any direct, hands-on patient care; instead, the nurse educates patients for health related issues over phones. The nurse notices that one of her patients, an 89-year-old male, takes Warfarin, an anticoagulant therapy, after a cardiovascular disease was diagnosed. Warfarin inhibits the enzyme vitamin K epoxide reductase to prevent the reduction of vitamin K, which is a step necessary for activation of clotting factors II, VII, IX, and X (Van Berkel, Crannage, & Murphy, 2013).
1- Talking about inspirations, I need to divide into three different categories: concept, style, and material. The idea for this series of drawings comes from human life cycle and I visualize it based on my personal surreal imagination. The human 's life cycle always start by a zygote, then the zygote becomes an embryo, after born there are two main stages, first is before adulthood when there are many conflicts and variances that shape the personality, another stage is the adulthood when the character is totally formed and all those conflicts become part of the personality. During the whole cycle, changes are needed for the evolution. I decided to show these changes with limbs and their different gestures which express diverse feelings.

The study will have an experimental design involving groups of three people, two of which will be told beforehand about what the experiment will be about. Subjects will be analyzed in a classroom setting where familiar people will interact with them. This will help subjects feel more comfortable and allow us to observe whether or not they fall into peer pressure when under their element. The comparing value will be their age and grade. The dependent variable will be how well the subject can follow instructions.
1. In your own words, how would you define "intelligence" and how does it differ from "information"? Use an example to make your case. a. Information is produced when data points are combined to answer a question an example would be the biometric system, it gathers height and weight can produce a BMI score and can then be put on a chat determine in you fall within the normal range for the country of the person.
Part III: Application of Terms (6 points each = 24%) Analepsis- The entire first chapter of Child 44 is an analepsis, or more commonly known as a flashback. This chapter takes the reader twenty years into the past in order to view what we later find out is Leo and his younger brother Andrei hunting a cat in the wild in order to feed their mother. Analepsis is also used in Child 44 when Leo is injected with a medicine in order to make him tell the truth.
This scientific question is, does the different kind of gum increase or decrease your concentration? This question was chose because many people in the world always are looking for some tips on what helps them concentrate, and chewing gum is a very easy way to help improve concentration. The Independent Variable is the type of gum, the Control Group is Bubble Gum, the Experimental Group is the Spearmint, the Dependent Variable is test scores, the Constant Variables are same timed test, same timer, and same brand of gum. The hypothesis for this science fair project is if spearmint gum is chewed then the person's concentration will be increased. This hypothesis was picked because spearmint gum is minty and the scientist thought that maybe mint impacted the brain the most.
Now since p-value is greater than the significance value, then the hypothesis is considered rejected. It therefore negates the claim that the mean number of ounces in each bottle is less than sixteen (16) therefore it is not true. It therefore follows that the customers’ complaints may be right but not all soda bottles have less than 16 ounces each as it may be claimed. There is need for appropriate measures to be taken by ensuring that the right number of ounces are in each bottle of soda.
