DeVry University Analyzing Arguments with Truth Tables Multiple Math Questions
This assignment consists of a total of 103 math questions. This is a topics in college math class which is a pretty easy math course. The assignment starts at 2.3 “Set Operations” up to and including 3.1-3.3. The score in each section must be an 80 or better. You do get multiple chances on each question. I am attaching samples of the math questions for reference and to make sure it’s something you can do. I will provide further instructions to the tutor who accepts the assignment.

A 2017 study examined a large sample of health records from a California health insurance for children born between 2000-10. The study found that 3103 children had a diagnosis of autism spectrum disorder (ASD) and the remaining 193,826 did not. Below is a summary table from the publication.

A 2015 study examined whether light-emitting eReaders at bedtime may impair sleep quality. A random sample of 12 healthy adults slept in the lab on two different days. In random order, participants read for 30 minutes a print book one night and a light-emitting eReader the other night. Scalp electrodes were used to measure how long (in minutes) it took participants to reach a deep sleep stage. On average, the subjects took 12.3 minutes longer to reach deep sleep with the eReader than with the book.
2 Points
Choose the appropriate layout to record data from this study.
2 Points
On average, it took healthy adults longer to reach deep sleep when they used an eReader compared to a print book (a “significant,” surprisingly substantial, difference). What conclusion can we draw from this study?

National College Athletic Association (NCAA) provides data on college sports injuries. When an injury occurs, the NCAA adds an entry to their database. The database does not track which player experienced the injury.
This figure below summarizes all injuries experienced by women’s collegiate volleyball players from 2005 to 2009. It shows what percent of all injuries were of each type. Injury types that made up less than 2% of all injuries were grouped together as “All other.”
Consider these two statements summarizing the findings:
A) Between 2005 and 2009, the most common type of injury reported by women collegiate volleyball players was a sprain.
B) Between 2005 and 2009, nearly half of all women collegiate volleyball players experienced either a sprain or a muscle tear.

A study assessed the effects of playing a computer game (solitaire) during lunch on snack behavior. A sample of 44 healthy adults was randomly assigned to eat lunch either with the computer game distraction or without distraction. All participants ate the same breakfast and lunch.
Thirty minutes after lunch, participants were offered cookies as a snack and were instructed to eat as many or as few cookies as they liked. Those who ate with the distraction ate on average 52 grams of cookies, compared with 27 grams for those who ate without the distraction — a surprisingly substantial (statistically significant) difference.
What can we reasonably conclude from this study?

New York State (excluding New York City) reported the deaths of all white men and black men who died from prostate cancer (PC) in 1994. The data are summarized below.
Overall, the death rates from prostate cancers were very similar for White men and Black men in New York State in 1994. This fact, however, obscures some stark differences between White men and Black men, where Black men clearly suffered disproportionately from prostate cancer. This paradox is due to the fact that

A study published in 2015 examined material-need insecurities (food insecurity, cost-related medication underuse, housing instability, and energy insecurity) among adults diagnosed with diabetes. The study collected data on a random sample of 411 adult diabetic patients treated in medical centers all over Massachusetts. It found that 64.1% of the patients who experienced food insecurity had a poor control of their diabetes, whereas 41.6% of the patients who didn’t experience any food insecurity had a poor control of their diabetes.

The pulse oximeter is an inexpensive and non-invasive device that assesses a person’s blood oxygen level (“oxygen saturation”) by shining light through the skin of a finger. It is commonly used to determine whether a COVID-19 patient should be admitted to the emergency room and how much oxygen to give them.
A 2020 study compared the reading from a pulse oximeter with the actual oxygen level in blood drawn from an artery, in a large sample of hospitalized patients who identified their race as Black or White. The findings are summarized in the figure below. The figure highlights the arterial oxygen saturation value 88% because of its clinical relevance in a number of medical decisions.
2 Points
Select the best option from the listed choices to fill in the “BLANKS” in the following sentence:
Among patients with a pulse oximeter reading of 91%, BLANK-1 of White patients and BLANK-2 of Black patients had actual arterial oxygen saturations below the 88% level.
BLANK-1:
BLANK-2:

The pulse oximeter performed worse overall for Black patients than for White patients, with data showing a tendency of the device to

In the article, the researchers stated that “Questions about pulse oximeter technology have been raised, given its original development in populations that were not racially diverse.”
To what statistical issue does this statement refer?

A study of the effect of vitamin E on vascular disease in smokers recruited 22 healthy young adult male smokers and randomly assigned them to take for four weeks either a vitamin E supplement pill or an identical-looking pill containing no vitamin E. The study used ultrasound to measure the participants’ arterial diameter (in millimeters) at the end of the study. The ultrasound operator was not told which participant had taken the vitamin E supplement.
Explain why this study does not have a case-control design.

Manatees are large aquatic mammals that were listed until recently as an endangered species in the United States. Florida has collected census data on manatee deaths for all years since 1977, except for 2020 when data collection was interrupted by the pandemic.

Question 3 – Confidence Intervals
Prompt
Of the students randomly chosen for your data set, what percent of students do not work any amount?
Sort the “work” column in ascending order to easily find the number of students who do not work and use that value to create a percentage. Watch this short video to learn how to sort the work column (Links to an external site.) in your data set.
Use the percentage in part a) to create a 95% confidence interval estimate for the percentage of all college students who do not work. (see concepts in Units 6 & 7 – Modules 14-19)
Show your work. You can either use the math-type feature in Canvas to write out your steps or you can take a picture and upload handwritten work.
Interpret your confidence interval in complete sentences. “We are 95% confident that…”
What is the margin of error for the confidence interval you found? What could you do to make the confidence interval more precise/smaller? Explain using complete sentences.
American Military University Noise Impact Analysis Problem
I’m working on a algebra discussion question and need an explanation and answer to help me learn.
If you are the planning engineer for an apartment complex your organization plans to build close to the highway and you know that your potential tenants will complain of traffic noise hazards. You want to assure them that you have adequately carried out the noise impact analysis. Given that the sea level pressure is 0.00002N/m, to ensure that pressure level does not exceed 10 decibels, the sound pressure of concern must be___________ (in N/m)
